157942-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157942-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,4 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157942-76:
(8*1)+(7*5)+(6*7)+(5*9)+(4*4)+(3*2)+(2*7)+(1*6)=172
172 % 10 = 2
So 157942-76-2 is a valid CAS Registry Number.
