Check Digit Verification of cas no
The CAS Registry Mumber 83938-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,3 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83938-73:
(7*8)+(6*3)+(5*9)+(4*3)+(3*8)+(2*7)+(1*3)=172
172 % 10 = 2
So 83938-73-2 is a valid CAS Registry Number.
