Check Digit Verification of cas no
The CAS Registry Mumber 93779-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93779-31:
(7*9)+(6*3)+(5*7)+(4*7)+(3*9)+(2*3)+(1*1)=178
178 % 10 = 8
So 93779-31-8 is a valid CAS Registry Number.
