133961-99-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133961-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,6 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133961-99:
(8*1)+(7*3)+(6*3)+(5*9)+(4*6)+(3*1)+(2*9)+(1*9)=146
146 % 10 = 6
So 133961-99-6 is a valid CAS Registry Number.
