80042-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80042-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,4 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80042-05:
(7*8)+(6*0)+(5*0)+(4*4)+(3*2)+(2*0)+(1*5)=83
83 % 10 = 3
So 80042-05-3 is a valid CAS Registry Number.
