6966-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6966-19-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,6 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6966-19:
(6*6)+(5*9)+(4*6)+(3*6)+(2*1)+(1*9)=134
134 % 10 = 4
So 6966-19-4 is a valid CAS Registry Number.
