1233953-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1233953-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,9,5 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233953-81:
(9*1)+(8*2)+(7*3)+(6*3)+(5*9)+(4*5)+(3*3)+(2*8)+(1*1)=155
155 % 10 = 5
So 1233953-81-5 is a valid CAS Registry Number.
