42421-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42421-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,2 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42421-51:
(7*4)+(6*2)+(5*4)+(4*2)+(3*1)+(2*5)+(1*1)=82
82 % 10 = 2
So 42421-51-2 is a valid CAS Registry Number.
