Check Digit Verification of cas no
The CAS Registry Mumber 188191-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188191-13:
(8*1)+(7*8)+(6*8)+(5*1)+(4*9)+(3*1)+(2*1)+(1*3)=161
161 % 10 = 1
So 188191-13-1 is a valid CAS Registry Number.
