149331-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149331-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,3 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 149331-58:
(8*1)+(7*4)+(6*9)+(5*3)+(4*3)+(3*1)+(2*5)+(1*8)=138
138 % 10 = 8
So 149331-58-8 is a valid CAS Registry Number.

Quinone methides with one or two phosphono-substituents in 7-position reacts with O-, N-, S- and C-nucleophiles by addition in 7-position.Key words: Arylmethanbisphosphonates; 7-phosphorylated quinonemethides; 31P-, 13C-NMR

REACTION OF DIETHYL PHOSPHONATE AND TRIETHYL PHOSPHITE WITH 3,5-DI-tert-BUTYL-4-HYDROXYBENZALDEHYDE

Ismagilov, R. K.,Moskva, V. V.,Bagautdinova, D. B.,Arkhipov, V. P.,Kopylova, L. Yu

, p. 2054 - 2057 (2007/10/02)

The short high-temperature reaction of diethyl phosphonate with 3,5-di-tert-butyl-4-hydroxybenzaldehyde at molar ratio 2:1 yields diethyl-2-ethoxy-3,5-di-tert-butyl-4-hydroxybenzylphosphonate instead of the expected diethyl-α-hydroxy-3,5-di-tert-butyl-4-hydroxybenzylphosphonate.The same reagents taken in a 3:1 ratio react to form tetraethyl-3,5-di-tert-butyl-4-hydroxybenzylidenebisphosphonate.The same bisphosphonate is formed on treating 3,5-di-tert-butyl-4-hydroxybenzaldehyde with an excess of triethyl phosphite.
