Check Digit Verification of cas no
The CAS Registry Mumber 157199-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,9 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157199-56:
(8*1)+(7*5)+(6*7)+(5*1)+(4*9)+(3*9)+(2*5)+(1*6)=169
169 % 10 = 9
So 157199-56-9 is a valid CAS Registry Number.
