166302-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166302-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,3,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 166302-28:
(8*1)+(7*6)+(6*6)+(5*3)+(4*0)+(3*2)+(2*2)+(1*8)=119
119 % 10 = 9
So 166302-28-9 is a valid CAS Registry Number.
