Check Digit Verification of cas no
The CAS Registry Mumber 17231-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17231-51:
(7*1)+(6*7)+(5*2)+(4*3)+(3*1)+(2*5)+(1*1)=85
85 % 10 = 5
So 17231-51-5 is a valid CAS Registry Number.
