840530-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 840530-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,0,5,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 840530-18:
(8*8)+(7*4)+(6*0)+(5*5)+(4*3)+(3*0)+(2*1)+(1*8)=139
139 % 10 = 9
So 840530-18-9 is a valid CAS Registry Number.
