Check Digit Verification of cas no
The CAS Registry Mumber 6214-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,1 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6214-28:
(6*6)+(5*2)+(4*1)+(3*4)+(2*2)+(1*8)=74
74 % 10 = 4
So 6214-28-4 is a valid CAS Registry Number.
