1192350-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1192350-23-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,3,5 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1192350-23:
(9*1)+(8*1)+(7*9)+(6*2)+(5*3)+(4*5)+(3*0)+(2*2)+(1*3)=134
134 % 10 = 4
So 1192350-23-4 is a valid CAS Registry Number.
