81729-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81729-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,2 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81729-45:
(7*8)+(6*1)+(5*7)+(4*2)+(3*9)+(2*4)+(1*5)=145
145 % 10 = 5
So 81729-45-5 is a valid CAS Registry Number.
