Check Digit Verification of cas no
The CAS Registry Mumber 173381-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,8 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173381-12:
(8*1)+(7*7)+(6*3)+(5*3)+(4*8)+(3*1)+(2*1)+(1*2)=129
129 % 10 = 9
So 173381-12-9 is a valid CAS Registry Number.
