22936-96-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22936-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,3 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22936-96:
(7*2)+(6*2)+(5*9)+(4*3)+(3*6)+(2*9)+(1*6)=125
125 % 10 = 5
So 22936-96-5 is a valid CAS Registry Number.

Trienediolates of hexadienoic acids in synthesis, synthesis of retinoic and nor-retinoic acids

Aurell, Maria J.,Carne, Ismael,Clar, Jose E.,Gil, Salvador,Mestres, Ramon,Parra, Margarita,Tortajada, Amparo

, p. 6089 - 6100 (1993)

Double deprotonation of either (E,E)-3-methyl-2,4-hexadienoic acid 2, or 4,6-dimethyldihydro-2-pyrone 3 generates apparently the same lithium trienediolate, which affords ω-hydroxy acids 9 on reaction with ketones 7. Hydroxy acids 9 are easily dehydrated to octatrienoic acids 5, which are structurally related to retinoic acid. Similarly, sorbic acid 1 leads to nor-retinoic acid analogs 6.
