Check Digit Verification of cas no
The CAS Registry Mumber 6420-43-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6420-43:
(6*6)+(5*4)+(4*2)+(3*0)+(2*4)+(1*3)=75
75 % 10 = 5
So 6420-43-5 is a valid CAS Registry Number.
