Check Digit Verification of cas no
The CAS Registry Mumber 2666-17-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,6 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2666-17:
(6*2)+(5*6)+(4*6)+(3*6)+(2*1)+(1*7)=93
93 % 10 = 3
So 2666-17-3 is a valid CAS Registry Number.
