Check Digit Verification of cas no
The CAS Registry Mumber 3626-41-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,2 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3626-41:
(6*3)+(5*6)+(4*2)+(3*6)+(2*4)+(1*1)=83
83 % 10 = 3
So 3626-41-3 is a valid CAS Registry Number.
