108319-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108319-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,1 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108319-31:
(8*1)+(7*0)+(6*8)+(5*3)+(4*1)+(3*9)+(2*3)+(1*1)=109
109 % 10 = 9
So 108319-31-9 is a valid CAS Registry Number.
