Check Digit Verification of cas no

The CAS Registry Mumber 144357-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144357-48:
(8*1)+(7*4)+(6*4)+(5*3)+(4*5)+(3*7)+(2*4)+(1*8)=132
132 % 10 = 2
So 144357-48-2 is a valid CAS Registry Number.

1H-Tetrazole Catalysed Reactions of Trialkyl Phosphites: Observation of a Five-membered Cyclic Hydrophosphorane Intermediate during the Transesterification

Watanabe, Yutaka,Maehara, Shin-ichi,Ozaki, Shoichiro

, p. 1879 - 1880 (2007/10/02)

1H-Tetrazole-catalysed transesterification of a trialkyl phosphite with an alcohol and a (31)P NMR experiment in the case of 4,4,5,5-tetramethyl-2-(3-phenylpropoxy)-1,3,2-dioxaphospholane showed the existence of the corresponding cyclic five-coordinate hydrophosphorane as an intermediate.
