77936-93-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77936-93-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,3 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77936-93:
(7*7)+(6*7)+(5*9)+(4*3)+(3*6)+(2*9)+(1*3)=187
187 % 10 = 7
So 77936-93-7 is a valid CAS Registry Number.
