Check Digit Verification of cas no
The CAS Registry Mumber 89-41-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89-41:
(4*8)+(3*9)+(2*4)+(1*1)=68
68 % 10 = 8
So 89-41-8 is a valid CAS Registry Number.
