Check Digit Verification of cas no
The CAS Registry Mumber 1501-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1501-50:
(6*1)+(5*5)+(4*0)+(3*1)+(2*5)+(1*0)=44
44 % 10 = 4
So 1501-50-4 is a valid CAS Registry Number.
