Check Digit Verification of cas no
The CAS Registry Mumber 71885-51-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,8 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71885-51:
(7*7)+(6*1)+(5*8)+(4*8)+(3*5)+(2*5)+(1*1)=153
153 % 10 = 3
So 71885-51-3 is a valid CAS Registry Number.
