1404491-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1404491-72-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,4,4,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1404491-72:
(9*1)+(8*4)+(7*0)+(6*4)+(5*4)+(4*9)+(3*1)+(2*7)+(1*2)=140
140 % 10 = 0
So 1404491-72-0 is a valid CAS Registry Number.
