Check Digit Verification of cas no
The CAS Registry Mumber 6373-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6373-20:
(6*6)+(5*3)+(4*7)+(3*3)+(2*2)+(1*0)=92
92 % 10 = 2
So 6373-20-2 is a valid CAS Registry Number.
