Check Digit Verification of cas no
The CAS Registry Mumber 83221-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83221-57:
(7*8)+(6*3)+(5*2)+(4*2)+(3*1)+(2*5)+(1*7)=112
112 % 10 = 2
So 83221-57-2 is a valid CAS Registry Number.
