Check Digit Verification of cas no
The CAS Registry Mumber 83-23-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83-23:
(4*8)+(3*3)+(2*2)+(1*3)=48
48 % 10 = 8
So 83-23-8 is a valid CAS Registry Number.
