1191081-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191081-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,0,8 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1191081-02:
(9*1)+(8*1)+(7*9)+(6*1)+(5*0)+(4*8)+(3*1)+(2*0)+(1*2)=123
123 % 10 = 3
So 1191081-02-3 is a valid CAS Registry Number.
