Check Digit Verification of cas no
The CAS Registry Mumber 6441-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6441-82:
(6*6)+(5*4)+(4*4)+(3*1)+(2*8)+(1*2)=93
93 % 10 = 3
So 6441-82-3 is a valid CAS Registry Number.
