40958-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40958-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,5 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40958-44:
(7*4)+(6*0)+(5*9)+(4*5)+(3*8)+(2*4)+(1*4)=129
129 % 10 = 9
So 40958-44-9 is a valid CAS Registry Number.
