328091-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 328091-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,0,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 328091-23:
(8*3)+(7*2)+(6*8)+(5*0)+(4*9)+(3*1)+(2*2)+(1*3)=132
132 % 10 = 2
So 328091-23-2 is a valid CAS Registry Number.
