1133248-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1133248-23-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,2,4 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1133248-23:
(9*1)+(8*1)+(7*3)+(6*3)+(5*2)+(4*4)+(3*8)+(2*2)+(1*3)=113
113 % 10 = 3
So 1133248-23-3 is a valid CAS Registry Number.
