Check Digit Verification of cas no
The CAS Registry Mumber 56240-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,2,4 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 56240-38:
(7*5)+(6*6)+(5*2)+(4*4)+(3*0)+(2*3)+(1*8)=111
111 % 10 = 1
So 56240-38-1 is a valid CAS Registry Number.
