135779-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135779-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135779-13:
(8*1)+(7*3)+(6*5)+(5*7)+(4*7)+(3*9)+(2*1)+(1*3)=154
154 % 10 = 4
So 135779-13-4 is a valid CAS Registry Number.

Intramolecular Participation of the Amide Group in Acid- and Base-catalysed Phosphonate Monoester Hydrolysis
Rahil, J.,Pratt, R. F.
, p. 947 - 950 (2007/10/02)
Rates of hydrolysis of monoaryl α-amidophosphonates in both acid and alkaline solutions are much greater than those of comparable compounds lacking the amido substituent; intramolecular nucleophilic catalysis seems likely.This phenomenon may be important
