Check Digit Verification of cas no

The CAS Registry Mumber 1309459-29-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309459-29:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*5)+(3*9)+(2*2)+(1*9)=167
167 % 10 = 7
So 1309459-29-7 is a valid CAS Registry Number.

An environmental friendly approach for the synthesis of highly substituted imidazoles using Br?nsted acidic ionic liquid, N-methyl-2-pyrrolidonium hydrogen sulfate, as reusable catalyst

Shaterian, Hamid Reza,Ranjbar, Mohammad

, p. 40 - 49 (2011)

Br?nsted acidic ionic liquid, N-methyl-2-pyrrolidonium hydrogen sulfate, has been used as an efficient and reusable catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under thermal solvent-free conditions in excellent yields.
