1173933-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173933-03-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,3 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1173933-03:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*3)+(3*3)+(2*0)+(1*3)=153
153 % 10 = 3
So 1173933-03-3 is a valid CAS Registry Number.
