Check Digit Verification of cas no
The CAS Registry Mumber 565197-96-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,5,1,9 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 565197-96:
(8*5)+(7*6)+(6*5)+(5*1)+(4*9)+(3*7)+(2*9)+(1*6)=198
198 % 10 = 8
So 565197-96-8 is a valid CAS Registry Number.
