5Check Digit Verification of cas no
The CAS Registry Mumber 6406-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 6406-50:
(6*6)+(5*4)+(4*0)+(3*6)+(2*5)+(1*0)=84
84 % 10 = 4
So 6406-50-4 is a valid CAS Registry Number.
