Check Digit Verification of cas no
The CAS Registry Mumber 81-98-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81-98:
(4*8)+(3*1)+(2*9)+(1*8)=61
61 % 10 = 1
So 81-98-1 is a valid CAS Registry Number.
