Check Digit Verification of cas no

The CAS Registry Mumber 144728-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,2 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144728-78:
(8*1)+(7*4)+(6*4)+(5*7)+(4*2)+(3*8)+(2*7)+(1*8)=149
149 % 10 = 9
So 144728-78-9 is a valid CAS Registry Number.

Enantioselective α-arylation of O-carbamates via sparteine-mediated lithiation and Negishi cross-coupling

Royal, Titouan,Baumgartner, Yann,Baudoin, Olivier

, p. 166 - 169 (2017/11/27)

A general and highly enantioselective arylation of carbamates derived from primary alcohols was developed by combining Hoppe's sparteine-mediated asymmetric lithiation with Negishi cross-coupling. Coupled with Aggarwal's lithiation-borylation sequence, the current method provides a short and divergent access to a variety of enantioenriched secondary and tertiary benzylic alcohols.
