1197055-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1197055-23-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,0,5 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1197055-23:
(9*1)+(8*1)+(7*9)+(6*7)+(5*0)+(4*5)+(3*5)+(2*2)+(1*3)=164
164 % 10 = 4
So 1197055-23-4 is a valid CAS Registry Number.
