94004-42-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94004-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94004-42:
(7*9)+(6*4)+(5*0)+(4*0)+(3*4)+(2*4)+(1*2)=109
109 % 10 = 9
So 94004-42-9 is a valid CAS Registry Number.
