Check Digit Verification of cas no

The CAS Registry Mumber 114460-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,4,6 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 114460-98:
(8*1)+(7*1)+(6*4)+(5*4)+(4*6)+(3*0)+(2*9)+(1*8)=109
109 % 10 = 9
So 114460-98-9 is a valid CAS Registry Number.

Chemoselective reductive alkynylation of tertiary amides by Ir and Cu(i) bis-metal sequential catalysis

Huang, Pei-Qiang,Ou, Wei,Han, Feng

, p. 11967 - 11970 (2016)

We report herein a convenient and versatile method for the direct reductive alkynylation of tertiary amides to give propargylic amines through sequential Ir-catalysed hydrosilylation-Cu(i)-catalysed alkynylation. The reactions proceed chemoselectively at the amide group in the presence of several sensitive functional groups including the very reactive aldehyde group on either the amide or the alkyne coupling partner. The method is general for tert-amides with or without α-hydrogen.
