330197-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330197-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,1,9 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 330197-82:
(8*3)+(7*3)+(6*0)+(5*1)+(4*9)+(3*7)+(2*8)+(1*2)=125
125 % 10 = 5
So 330197-82-5 is a valid CAS Registry Number.
