Check Digit Verification of cas no
The CAS Registry Mumber 6252-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6252-73:
(6*6)+(5*2)+(4*5)+(3*2)+(2*7)+(1*3)=89
89 % 10 = 9
So 6252-73-9 is a valid CAS Registry Number.
