99302-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99302-38-2 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, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99302-38:
(7*9)+(6*9)+(5*3)+(4*0)+(3*2)+(2*3)+(1*8)=152
152 % 10 = 2
So 99302-38-2 is a valid CAS Registry Number.

Synthesis of 8-, 9-, 12-, and 13-mono-13C-retinal
Pardoen, J. A.,Mulder, P. P. J.,Berg, E. M. M. van den,Lugtenburg, J.
, p. 1431 - 1435 (2007/10/02)
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.
