440345-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 440345-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,3,4 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 440345-33:
(8*4)+(7*4)+(6*0)+(5*3)+(4*4)+(3*5)+(2*3)+(1*3)=115
115 % 10 = 5
So 440345-33-5 is a valid CAS Registry Number.
