Check Digit Verification of cas no
The CAS Registry Mumber 153717-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,1 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153717-32:
(8*1)+(7*5)+(6*3)+(5*7)+(4*1)+(3*7)+(2*3)+(1*2)=129
129 % 10 = 9
So 153717-32-9 is a valid CAS Registry Number.
