Check Digit Verification of cas no
The CAS Registry Mumber 10316-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,1 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10316-52:
(7*1)+(6*0)+(5*3)+(4*1)+(3*6)+(2*5)+(1*2)=56
56 % 10 = 6
So 10316-52-6 is a valid CAS Registry Number.
