Check Digit Verification of cas no

The CAS Registry Mumber 1256241-82-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256241-82:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*4)+(3*1)+(2*8)+(1*2)=143
143 % 10 = 3
So 1256241-82-3 is a valid CAS Registry Number.

Highly chemoselective palladium-catalyzed cross-trimerization between alkyne and alkenes leading to 1,3,5-trienes or 1,2,4,5-tetrasubstituted benzenes with dioxygen

Zhou, Peng,Huang, Liangbin,Jiang, Huanfeng,Wang, Azhong,Li, Xianwei

, p. 8279 - 8282 (2010)

A palladium-catalyzed 1:2 linear/cyclic cross-trimerization of alkyne with alkenes using molecular oxygen as the sole oxidant has been reported for the first time. A series of 1,3,5-trienes and 1,2,4,5-tetrasubstituted benzenes are obtained with high chemoselectivity respectively and mechanisms of these reactions are proposed based on some controlled examination.
