55003-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55003-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,0 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55003-40:
(7*5)+(6*5)+(5*0)+(4*0)+(3*3)+(2*4)+(1*0)=82
82 % 10 = 2
So 55003-40-2 is a valid CAS Registry Number.
