330830-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330830-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,8,3 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 330830-31:
(8*3)+(7*3)+(6*0)+(5*8)+(4*3)+(3*0)+(2*3)+(1*1)=104
104 % 10 = 4
So 330830-31-4 is a valid CAS Registry Number.
