Check Digit Verification of cas no
The CAS Registry Mumber 73316-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,1 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73316-22:
(7*7)+(6*3)+(5*3)+(4*1)+(3*6)+(2*2)+(1*2)=110
110 % 10 = 0
So 73316-22-0 is a valid CAS Registry Number.
