Check Digit Verification of cas no
The CAS Registry Mumber 98-61-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98-61:
(4*9)+(3*8)+(2*6)+(1*1)=73
73 % 10 = 3
So 98-61-3 is a valid CAS Registry Number.
