Check Digit Verification of cas no
The CAS Registry Mumber 5197-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5197-81:
(6*5)+(5*1)+(4*9)+(3*7)+(2*8)+(1*1)=109
109 % 10 = 9
So 5197-81-9 is a valid CAS Registry Number.
