1196459-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1196459-18-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,6,4,5 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1196459-18:
(9*1)+(8*1)+(7*9)+(6*6)+(5*4)+(4*5)+(3*9)+(2*1)+(1*8)=193
193 % 10 = 3
So 1196459-18-3 is a valid CAS Registry Number.
