Check Digit Verification of cas no

The CAS Registry Mumber 1421859-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,8,5 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1421859-13:
(9*1)+(8*4)+(7*2)+(6*1)+(5*8)+(4*5)+(3*9)+(2*1)+(1*3)=153
153 % 10 = 3
So 1421859-13-3 is a valid CAS Registry Number.

Palladium-catalyzed picolinamide-directed alkylation of unactivated C(sp3)-H bonds with alkyl iodides

Zhang, Shu-Yu,He, Gang,Nack, William A.,Zhao, Yingsheng,Li, Qiong,Chen, Gong

, p. 2124 - 2127 (2013)

We report an efficient method for the alkylation of γ-C(sp 3)-H bonds of picolinamide-protected aliphatic amine substrates with primary alkyl iodides via palladium catalysis. Ag2CO3 and dibenzyl phosphate, (BnO)2PO2H, are critical promoters of this reaction. These reactions provide a convenient and straightforward method for the preparation of high-value N-containing products from readily available amine and alkyl iodide precursors.
