72139-20-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72139-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,3 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72139-20:
(7*7)+(6*2)+(5*1)+(4*3)+(3*9)+(2*2)+(1*0)=109
109 % 10 = 9
So 72139-20-9 is a valid CAS Registry Number.
