116507-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116507-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,0 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116507-44:
(8*1)+(7*1)+(6*6)+(5*5)+(4*0)+(3*7)+(2*4)+(1*4)=109
109 % 10 = 9
So 116507-44-9 is a valid CAS Registry Number.
