84078-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84078-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84078-23:
(7*8)+(6*4)+(5*0)+(4*7)+(3*8)+(2*2)+(1*3)=139
139 % 10 = 9
So 84078-23-9 is a valid CAS Registry Number.
