4542-84-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4542-84-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4542-84:
(6*4)+(5*5)+(4*4)+(3*2)+(2*8)+(1*4)=91
91 % 10 = 1
So 4542-84-1 is a valid CAS Registry Number.
