Check Digit Verification of cas no
The CAS Registry Mumber 4197-00-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4197-00:
(6*4)+(5*1)+(4*9)+(3*7)+(2*0)+(1*0)=86
86 % 10 = 6
So 4197-00-6 is a valid CAS Registry Number.
