1044508-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1044508-63-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,0 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1044508-63:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*0)+(3*8)+(2*6)+(1*3)=125
125 % 10 = 5
So 1044508-63-5 is a valid CAS Registry Number.
