6-7Check Digit Verification of cas no
The CAS Registry Mumber 12219-24-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,1 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.Calculate Digit Verification of CAS Registry Number 12219-24:
(7*1)+(6*2)+(5*2)+(4*1)+(3*9)+(2*2)+(1*4)=68
68 % 10 = 8
So 12219-24-8 is a valid CAS Registry Number.
