40628-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40628-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,2 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40628-17:
(7*4)+(6*0)+(5*6)+(4*2)+(3*8)+(2*1)+(1*7)=99
99 % 10 = 9
So 40628-17-9 is a valid CAS Registry Number.
