Check Digit Verification of cas no

The CAS Registry Mumber 1383841-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,8,4 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1383841-31:
(9*1)+(8*3)+(7*8)+(6*3)+(5*8)+(4*4)+(3*1)+(2*3)+(1*1)=173
173 % 10 = 3
So 1383841-31-3 is a valid CAS Registry Number.

Copper-catalyzed cross-coupling of nonactivated secondary alkyl halides and tosylates with secondary alkyl grignard reagents

Yang, Chu-Ting,Zhang, Zhen-Qi,Liang, Jun,Liu, Jing-Hui,Lu, Xiao-Yu,Chen, Huan-Huan,Liu, Lei

supporting information; experimental part, p. 11124 - 11127 (2012/08/28)

Practical catalytic cross-coupling of secondary alkyl electrophiles with secondary alkyl nucleophiles under Cu catalysis has been realized. The use of TMEDA and LiOMe is critical for the success of the reaction. This cross-coupling reaction occurs via an SN2 mechanism with inversion of configuration and therefore provides a general approach for the stereocontrolled formation of C-C bonds between two tertiary carbons from chiral secondary alcohols.
