1108729-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1108729-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,8,7,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1108729-40:
(9*1)+(8*1)+(7*0)+(6*8)+(5*7)+(4*2)+(3*9)+(2*4)+(1*0)=143
143 % 10 = 3
So 1108729-40-3 is a valid CAS Registry Number.

A regioselective synthesis is reported of a series of polysubstituted 1,2,4-triazoles and 4,4′- and 5,5′-bi-(1,2,4-triazoles) via 1,3-dipolar cycloaddition reactions of nitrilimines with some aza- and diaza-butadiene derivatives.
