Check Digit Verification of cas no
The CAS Registry Mumber 157188-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,8 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157188-11:
(8*1)+(7*5)+(6*7)+(5*1)+(4*8)+(3*8)+(2*1)+(1*1)=149
149 % 10 = 9
So 157188-11-9 is a valid CAS Registry Number.
