304022-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 304022-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,0,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 304022-31:
(8*3)+(7*0)+(6*4)+(5*0)+(4*2)+(3*2)+(2*3)+(1*1)=69
69 % 10 = 9
So 304022-31-9 is a valid CAS Registry Number.
