Check Digit Verification of cas no

The CAS Registry Mumber 1292320-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,3,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1292320-69:
(9*1)+(8*2)+(7*9)+(6*2)+(5*3)+(4*2)+(3*0)+(2*6)+(1*9)=144
144 % 10 = 4
So 1292320-69-4 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.
