Check Digit Verification of cas no

The CAS Registry Mumber 181519-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,1 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181519-99:
(8*1)+(7*8)+(6*1)+(5*5)+(4*1)+(3*9)+(2*9)+(1*9)=153
153 % 10 = 3
So 181519-99-3 is a valid CAS Registry Number.

Synthesis and anticonvulsant activity of some spiro compounds derived from barbituric and thiobarbituric acids: Part I

Osman,Kandeel,Said,Ahmed

, p. 1073 - 1078 (2007/10/03)

Divinyl ketones (1), prepared by the condensation of acetone with the appropriate aromatic aldehydes, on Michael addition with barbituric and thiobarbituric acids afford the desired spiro compounds (2a-j). The ketoximes (3a-j) obtained from 2a-j on Beckmann transformation by treatment with PCl5 furnish the spiro azepines (4a-j). Alkylation of some of the compounds 2 afford the anticipated N-substituted products (5a-i). Preliminary pharmacological screening of some of the new compounds reveal their anticonvulsant activity.
