87922-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87922-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,2 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87922-15:
(7*8)+(6*7)+(5*9)+(4*2)+(3*2)+(2*1)+(1*5)=164
164 % 10 = 4
So 87922-15-4 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.
