99302-17-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99302-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,0 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99302-17:
(7*9)+(6*9)+(5*3)+(4*0)+(3*2)+(2*1)+(1*7)=147
147 % 10 = 7
So 99302-17-7 is a valid CAS Registry Number.

The 8-, 9-, 12-, and 13-mono-13C-retinals were synthesized with >98percent chemical purity and 93percent 13C incorporation from 13C-labelled acetonitrile.Their 13C-13C and 13C-1H nmr coupling constants were determined.
