Check Digit Verification of cas no
The CAS Registry Mumber 101-72-4 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, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 101-72:
(5*1)+(4*0)+(3*1)+(2*7)+(1*2)=24
24 % 10 = 4
So 101-72-4 is a valid CAS Registry Number.
