Check Digit Verification of cas no

The CAS Registry Mumber 41902-36-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,0 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41902-36:
(7*4)+(6*1)+(5*9)+(4*0)+(3*2)+(2*3)+(1*6)=97
97 % 10 = 7
So 41902-36-7 is a valid CAS Registry Number.

Synthetic studies on CP-225,917 and CP-263,114: Access to advanced tetracyclic systems by intramolecular conjugate displacement and [2,3]-wittig rearrangement

Malihi, Farzad,Clive, Derrick L. J.,Chang, Che-Chien,Minaruzzaman

, p. 996 - 1013 (2013/04/10)

An advanced intermediate related to the structures of CP-225,917 and CP-263,114 was constructed by a sequence based on the use of Grob-like fragmentation, intramolecular conjugate displacement, and [2,3]-Wittig rearrangement. A variant of the [2,3]-Wittig rearrangement was developed.
