71691-01-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71691-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,9 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71691-01:
(7*7)+(6*1)+(5*6)+(4*9)+(3*1)+(2*0)+(1*1)=125
125 % 10 = 5
So 71691-01-5 is a valid CAS Registry Number.
