1004518-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1004518-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,4,5,1 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1004518-90:
(9*1)+(8*0)+(7*0)+(6*4)+(5*5)+(4*1)+(3*8)+(2*9)+(1*0)=104
104 % 10 = 4
So 1004518-90-4 is a valid CAS Registry Number.
