54812-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54812-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,1 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54812-42:
(7*5)+(6*4)+(5*8)+(4*1)+(3*2)+(2*4)+(1*2)=119
119 % 10 = 9
So 54812-42-9 is a valid CAS Registry Number.
