Check Digit Verification of cas no
The CAS Registry Mumber 6439-53-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6439-53:
(6*6)+(5*4)+(4*3)+(3*9)+(2*5)+(1*3)=108
108 % 10 = 8
So 6439-53-8 is a valid CAS Registry Number.
