Check Digit Verification of cas no

The CAS Registry Mumber 474087-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,0,8 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 474087-63:
(8*4)+(7*7)+(6*4)+(5*0)+(4*8)+(3*7)+(2*6)+(1*3)=173
173 % 10 = 3
So 474087-63-3 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 (2002)

(+)-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.
