55-88-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55-88-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55-88:
(4*5)+(3*5)+(2*8)+(1*8)=59
59 % 10 = 9
So 55-88-9 is a valid CAS Registry Number.

(2E)-4-hydroxyalk-2-enals and 2-substituted furans as products of reactions of (2E)-4,4-dimethoxybut-2-enal with Grignard compounds

Garibyan,Ovanesyan,Makaryan,Petrosyan,Chobanyan

experimental part, p. 406 - 409 (2010/09/12)

Methods have been developed for the synthesis of (2E)-1,1-dimethoxyalk-2- en-4-ols and (2E)-4-hydroxyalk-2-enals by reaction of (2E)-4,4-dimethoxybut-2- enals and Grignard compounds. Thermal isomerization of (2E)-4-hydroxyalk-2-enals gave the corresponding 2-alkylfurans.
