55042-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55042-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55042-80:
(7*5)+(6*5)+(5*0)+(4*4)+(3*2)+(2*8)+(1*0)=103
103 % 10 = 3
So 55042-80-3 is a valid CAS Registry Number.
