Check Digit Verification of cas no

The CAS Registry Mumber 1048703-30-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,8,7,0 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1048703-30:
(9*1)+(8*0)+(7*4)+(6*8)+(5*7)+(4*0)+(3*3)+(2*3)+(1*0)=135
135 % 10 = 5
So 1048703-30-5 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.
