Check Digit Verification of cas no
The CAS Registry Mumber 72198-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72198-83:
(7*7)+(6*2)+(5*1)+(4*9)+(3*8)+(2*8)+(1*3)=145
145 % 10 = 5
So 72198-83-5 is a valid CAS Registry Number.
