Check Digit Verification of cas no
The CAS Registry Mumber 40240-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,4 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40240-41:
(7*4)+(6*0)+(5*2)+(4*4)+(3*0)+(2*4)+(1*1)=63
63 % 10 = 3
So 40240-41-3 is a valid CAS Registry Number.
