Check Digit Verification of cas no
The CAS Registry Mumber 158813-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,8,1 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158813-71:
(8*1)+(7*5)+(6*8)+(5*8)+(4*1)+(3*3)+(2*7)+(1*1)=159
159 % 10 = 9
So 158813-71-9 is a valid CAS Registry Number.
