1159692-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159692-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,6,9 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1159692-52:
(9*1)+(8*1)+(7*5)+(6*9)+(5*6)+(4*9)+(3*2)+(2*5)+(1*2)=190
190 % 10 = 0
So 1159692-52-0 is a valid CAS Registry Number.
