Check Digit Verification of cas no

The CAS Registry Mumber 95263-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,2,6 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 95263-16:
(7*9)+(6*5)+(5*2)+(4*6)+(3*3)+(2*1)+(1*6)=144
144 % 10 = 4
So 95263-16-4 is a valid CAS Registry Number.

HIGH PRESSURE APPROACH TO THE SYNTHESIS OF 7-PHOSPHANORBORNADIENES FORM λ5-PHOSPHOLE OXIDES AND DIALKYL ACETYLENEDICARBOXYLATES

Matsumoto, Kiyoshi,Hashimoto, Shiro,Otani, Shinichi

, p. 2713 - 2717 (2007/10/02)

Reactions of 1,2,3,4,5-pentaphenylphosphole oxide (4a) with dimethyl and di-t-butyl acetylenedicarboxylates (5a, b) under high pressure afford the tetraphenylphthalates (7a, b) along with the 7-phosphanorbornadiene derivatives (6a, b).The latter adducts h
