Check Digit Verification of cas no

The CAS Registry Mumber 1257410-68-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,1 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1257410-68:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*1)+(3*0)+(2*6)+(1*8)=146
146 % 10 = 6
So 1257410-68-6 is a valid CAS Registry Number.

Heterocyclic synthesis using nitrilimines: Part 14. Synthesis of new pyrazole derivatives

Dalloul, Hany M.

experimental part, p. 529 - 535 (2010/12/18)

A new series of 1, 3, 4, 5-tetrasubstituted pyrazoles have been synthesized by the 1, 3-dipolar cycloaddition of suitable nitrilimines to 3-propylidene and 3-benzylidene-phthalide. Both analytical and spectroscopic data of all the synthesized compounds are in full agreement with the proposed structures. tuebitak.
