133531-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133531-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133531-74:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*1)+(2*7)+(1*4)=105
105 % 10 = 5
So 133531-74-5 is a valid CAS Registry Number.
