440370-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 440370-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,3,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 440370-06:
(8*4)+(7*4)+(6*0)+(5*3)+(4*7)+(3*0)+(2*0)+(1*6)=109
109 % 10 = 9
So 440370-06-9 is a valid CAS Registry Number.
