5Check Digit Verification of cas no
The CAS Registry Mumber 61931-02-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,3 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 61931-02:
(7*6)+(6*1)+(5*9)+(4*3)+(3*1)+(2*0)+(1*2)=110
110 % 10 = 0
So 61931-02-0 is a valid CAS Registry Number.
