Check Digit Verification of cas no

The CAS Registry Mumber 136778-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,7 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136778-40:
(8*1)+(7*3)+(6*6)+(5*7)+(4*7)+(3*8)+(2*4)+(1*0)=160
160 % 10 = 0
So 136778-40-0 is a valid CAS Registry Number.

A short and general approach to the synthesis of styryllactones: (+)-Goniodiol, its acetates and β-trifluoromethyl derivative, (+)-7-epi-Goniodiol and (+)-9-deoxygoniopypyrone

Chen, Jian,Lin, Guo-Qiang,Wang, Zhi-Min,Liu, Han-Quan

, p. 1265 - 1268 (2007/10/03)

(+)-Goniodiol, its acetates and β-trifluoromethyl derivative, (+)-7-epi-Goniodiol and (+)-9-deoxygoniopypyrone, the representatives of styryllactones have been synthesized in a short and general way. The key steps involve the regioselective asymmetric dihydroxylation and the palladium-catalyzed cross-coupling of cyclic allylic carbonate with vinyltributylstannane.

Styrylpyrone Derivatives from Goniothalamus dolichocarpus

Goh, S. H.,Ee, G. C. L.,Chuah, C. H.,Wei, Chen

Styrylpyrone derivatives (+)-goniothalamin (1), (+)-goniothalamin epoxide (2) and (-)-iso-5-deoxygoniopypyrone (4b), and the acetogenin (+)-annonacin (7) were bioactive compounds isolated from the stem bark of Goniothalamus dolichocarpus.The stereochemica

Structure and Stereochemistry of Four New 5,6-Dihydro-2-pyrones from Goniothalamus sesquipedalis and Goniothalamus grifithii

Talapatra, Sunil K.,Basu, Dipankar,Deb, Tullika,Goswami, Shyamaprosad,Talapatra, Bani

, p. 29 - 34 (2007/10/02)

The leaves and twigs of Goniothalamus sesquipedalis Wall (Annonaceae) afford four new 6-(7,8-dihydrostyryl)-5,6-dihydro-2-pyrones, having in each case hydroxy and/or acetoxy functions at C-7 and C-8.The detailed high resolution PMR and other spectral analyses along with their chemical interconversions reveal their structures as 6-(7,8-dihydro-7,8-diacetoxystyryl)-5,6-dihydro-2-pyrone (II), 6-(7,8-dihydro-7-acetoxy-8-hydroxystyryl)-5,6-dihydro-2-pyrone (III), 6-(7,8-dihydro-7,8-dihydroxystyryl)-5,6-dihydro-2-pyrone (IV) and 6-(7,8-dihydro-7,8-dihydroxystyryl)-5,6-dihydro-5-hydroxy-2-pyrone (V).Compounds II, III and IV have also been isolated from the bark of Goniothalamus grifithii Hook.F and T.Thoms.The 7,8-erythro configuration is revealed for the above dihydropyrones from the coupling constants of the vicinal protons.Biogenetic considerations lead us to propose 6,7-threo and 7,8-erythro-configurations leading to 6(S), 7(S) and 8(S) configuration in these dihydropyrones.The stereochemistry of C-5 in V remains unsettled.
