330189-37-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 330189-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,1,8 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 330189-37:
(8*3)+(7*3)+(6*0)+(5*1)+(4*8)+(3*9)+(2*3)+(1*7)=122
122 % 10 = 2
So 330189-37-2 is a valid CAS Registry Number.
