Check Digit Verification of cas no

The CAS Registry Mumber 1440524-48-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,5,2 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1440524-48:
(9*1)+(8*4)+(7*4)+(6*0)+(5*5)+(4*2)+(3*4)+(2*4)+(1*8)=130
130 % 10 = 0
So 1440524-48-0 is a valid CAS Registry Number.

Enantioselective phase-transfer catalytic α-alkylation of 2-methylbenzyl tert-butyl malonates

Ha, Min Woo,Hong, Suckchang,Park, Cheonhyoung,Park, Yohan,Lee, Jihye,Kim, Mi-Hyun,Lee, Jihoon,Park, Hyeung-Geun

, p. 4030 - 4039 (2013)

A new asymmetric synthetic method to prepare α,α- dialkylmalonates for the construction of a quaternary carbon center via phase-transfer catalytic (PTC) alkylation has been developed. Enantioselective α-alkylation of 2-methylbenzyl tert-butyl α-methylmalonates under phase-transfer catalytic conditions in the presence of (S,S)-3,4,5- trifluorophenyl-NAS bromide (10) afforded the corresponding α,α- dialkylmalonates in high chemical (up to 99%) and optical yields (up to 91% ee), which were selectively hydrolyzed to malonic monoacids under alkali basic conditions for conversion to versatile chiral intermediates.
