Check Digit Verification of cas no

The CAS Registry Mumber 349431-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,4,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 349431-98:
(8*3)+(7*4)+(6*9)+(5*4)+(4*3)+(3*1)+(2*9)+(1*8)=167
167 % 10 = 7
So 349431-98-7 is a valid CAS Registry Number.

Selective formation of secondary amides via the copper-catalyzed cross-coupling of alkylboronic acids with primary amides

Rossi, Steven A.,Shimkin, Kirk W.,Xu, Qun,Mori-Quiroz, Luis M.,Watson, Donald A.

supporting information, p. 2314 - 2317 (2013/06/05)

For the first time, a general catalytic procedure for the cross-coupling of primary amides and alkylboronic acids is demonstrated. The key to the success of this reaction was the identification of a mild base (NaOSiMe3) and oxidant (di-tert-butyl peroxide) to promote the copper-catalyzed reaction in high yield. This transformation provides a facile, high-yielding method for the monoalkylation of amides.
