Check Digit Verification of cas no

The CAS Registry Mumber 1426162-41-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,1,6 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1426162-41:
(9*1)+(8*4)+(7*2)+(6*6)+(5*1)+(4*6)+(3*2)+(2*4)+(1*1)=135
135 % 10 = 5
So 1426162-41-5 is a valid CAS Registry Number.

Chemo and diastereoselective conjugate addition of Grignard reagents on parthenin, a bioactive natural sesquiterpene lactone

Kashanna, Jajula,Jangili, Paramesh,Kumar, Rathod Aravind,Rao, Bethapudirr Rama

, p. 1634 - 1637 (2013)

The conjugate addition on a natural bioactive pseudoguaianolide sesquiterpene lactone parthenin with various Grignard reagents leads to 13-C alkylated products chemo and diastereoselectively in fair overall yields. Compared with other Grignard reagents vinyl and smaller straight chain alkyl Grignard reagents gave better yields.
