79999-63-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 79999-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79999-63:
(7*7)+(6*9)+(5*9)+(4*9)+(3*9)+(2*6)+(1*3)=226
226 % 10 = 6
So 79999-63-6 is a valid CAS Registry Number.
