Check Digit Verification of cas no
The CAS Registry Mumber 101-50-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101-50:
(5*1)+(4*0)+(3*1)+(2*5)+(1*0)=18
18 % 10 = 8
So 101-50-8 is a valid CAS Registry Number.
