Check Digit Verification of cas no
The CAS Registry Mumber 1118-40-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1118-40:
(6*1)+(5*1)+(4*1)+(3*8)+(2*4)+(1*0)=47
47 % 10 = 7
So 1118-40-7 is a valid CAS Registry Number.
