Check Digit Verification of cas no

The CAS Registry Mumber 85864-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,6 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85864-05:
(7*8)+(6*5)+(5*8)+(4*6)+(3*4)+(2*0)+(1*5)=167
167 % 10 = 7
So 85864-05-7 is a valid CAS Registry Number.

Synthesis of Acronycine Isosters

Reisch, Johannes,Mester, Iuliu,Aly, Samir M. El-Moghazy

, p. 219 - 223 (2007/10/02)

The synthesis of the two key intermediates 6,8-dihydroxy-10-methylbenzonaphthyridin-5(10H)-one (4b) and 6,8-dihydroxy-5H-benzopyranopyridin-5-one (4d) for the synthesis of acronycine isosteres is described.The condensation of (4b) with 3-chloro-3-methylbut-1-yne afforded three isomers (5), (6), and (7), from which it was possible to distinguish between the angular isomer (5) and the linear isomer (6) with the aid of 13C n.m.r. spectroscopy.The condensation of (4d) with 3-chloro-3-methylbut-1-yne yielded only one product (8).The action of dimethyl sulphate on 6-hydroxy-3,3-dimethyl-3H-pyranochromenopyridin-7-one (8) as well as on 6,8-dimethoxy-5H-benzopyranopyridin-5-one (3b) is also reported.
