Check Digit Verification of cas no
The CAS Registry Mumber 2672-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,7 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2672-81:
(6*2)+(5*6)+(4*7)+(3*2)+(2*8)+(1*1)=93
93 % 10 = 3
So 2672-81-3 is a valid CAS Registry Number.
