18319-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18319-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,1 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18319-40:
(7*1)+(6*8)+(5*3)+(4*1)+(3*9)+(2*4)+(1*0)=109
109 % 10 = 9
So 18319-40-9 is a valid CAS Registry Number.
