1173502-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173502-23-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,5,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1173502-23:
(9*1)+(8*1)+(7*7)+(6*3)+(5*5)+(4*0)+(3*2)+(2*2)+(1*3)=122
122 % 10 = 2
So 1173502-23-2 is a valid CAS Registry Number.
