328066-15-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 328066-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,0,6 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 328066-15:
(8*3)+(7*2)+(6*8)+(5*0)+(4*6)+(3*6)+(2*1)+(1*5)=135
135 % 10 = 5
So 328066-15-5 is a valid CAS Registry Number.
