Check Digit Verification of cas no
The CAS Registry Mumber 83-61-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83-61:
(4*8)+(3*3)+(2*6)+(1*1)=54
54 % 10 = 4
So 83-61-4 is a valid CAS Registry Number.
