Check Digit Verification of cas no
The CAS Registry Mumber 61724-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,2 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 61724-50:
(7*6)+(6*1)+(5*7)+(4*2)+(3*4)+(2*5)+(1*0)=113
113 % 10 = 3
So 61724-50-3 is a valid CAS Registry Number.
