Check Digit Verification of cas no
The CAS Registry Mumber 6448-96-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6448-96:
(6*6)+(5*4)+(4*4)+(3*8)+(2*9)+(1*6)=120
120 % 10 = 0
So 6448-96-0 is a valid CAS Registry Number.
