Check Digit Verification of cas no

The CAS Registry Mumber 138037-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138037-04:
(8*1)+(7*3)+(6*8)+(5*0)+(4*3)+(3*7)+(2*0)+(1*4)=114
114 % 10 = 4
So 138037-04-4 is a valid CAS Registry Number.

Site-Selective Silylation of Aliphatic C-H Bonds Mediated by [1,5]-Hydrogen Transfer: Synthesis of α-Sila Benzamides

Liu, Pei,Tang, Jinghua,Zeng, Xiaoming

, p. 5536 - 5539 (2016/11/17)

The first example of site-selective silylation of C(sp3)-H bonds mediated by a [1,5]-hydrogen transfer is reported. This reaction occurs selectively at the α-position of benzamides with a combination of tert-butylmagnesium chloride and a catalytic amount of 4,4′-di-tert-butylbipyridine (dtbpy) ligand and provides a facile route for the creation of biologically interesting α-sila benzamides. Late-stage functionalization of the incorporated silyl moieties facilitates the synthesis of N-formyl, cis-enamine, β-hydroxyl, amino, and pyrrole-containing derivatives.
