1044579-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1044579-48-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,7 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1044579-48:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*7)+(3*9)+(2*4)+(1*8)=157
157 % 10 = 7
So 1044579-48-7 is a valid CAS Registry Number.
