Check Digit Verification of cas no

The CAS Registry Mumber 81841-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81841-22:
(7*8)+(6*1)+(5*8)+(4*4)+(3*1)+(2*2)+(1*2)=127
127 % 10 = 7
So 81841-22-7 is a valid CAS Registry Number.

SYNTHESIS OF CIS AND TRANS DECALINS BY BORON ANNULATION

Levine, Eric J.,Bryson, Thomas A.

, p. 271 - 275 (2007/10/02)

Hydroboration and cyanidation of 1,4-diene 1 afforded bicyclic compounds 2 (trans) and 3 (cis).Boron annulation of diene 7 (R=CH3) yielded cis and trans decalones.Simple and competitive hydroboration of 1,4-dienes 1 and 7 (R=CH3 and SΦ) were analyzed for regio- and stereoselectivity.
