Check Digit Verification of cas no
The CAS Registry Mumber 13720-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,2 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13720-48:
(7*1)+(6*3)+(5*7)+(4*2)+(3*0)+(2*4)+(1*8)=84
84 % 10 = 4
So 13720-48-4 is a valid CAS Registry Number.
