6Check Digit Verification of cas no
The CAS Registry Mumber 12237-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 12237-02:
(7*1)+(6*2)+(5*2)+(4*3)+(3*7)+(2*0)+(1*2)=64
64 % 10 = 4
So 12237-02-4 is a valid CAS Registry Number.
