84253-30-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84253-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84253-30:
(7*8)+(6*4)+(5*2)+(4*5)+(3*3)+(2*3)+(1*0)=125
125 % 10 = 5
So 84253-30-5 is a valid CAS Registry Number.
