1440237-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440237-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,2,3 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1440237-35:
(9*1)+(8*4)+(7*4)+(6*0)+(5*2)+(4*3)+(3*7)+(2*3)+(1*5)=123
123 % 10 = 3
So 1440237-35-3 is a valid CAS Registry Number.
