Check Digit Verification of cas no
The CAS Registry Mumber 40288-30-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,8 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40288-30:
(7*4)+(6*0)+(5*2)+(4*8)+(3*8)+(2*3)+(1*0)=100
100 % 10 = 0
So 40288-30-0 is a valid CAS Registry Number.
