40519-95-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40519-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,1 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40519-95:
(7*4)+(6*0)+(5*5)+(4*1)+(3*9)+(2*9)+(1*5)=107
107 % 10 = 7
So 40519-95-7 is a valid CAS Registry Number.
