Check Digit Verification of cas no

The CAS Registry Mumber 221179-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,7 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221179-29:
(8*2)+(7*2)+(6*1)+(5*1)+(4*7)+(3*9)+(2*2)+(1*9)=109
109 % 10 = 9
So 221179-29-9 is a valid CAS Registry Number.

First efficient two-step/one-pot zirconium (IV)isopropoxide-mediated reductive amination of carbonyl compounds

Pieri, Cyril,Brunel, Jean Michel

, p. 448 - 456 (2015/06/22)

An efficient method for the synthesis of various primary and secondary amines through a zirconium(IV) isopropoxide-mediated reductive amination reaction of aldehydes and ketones is reported. A series of different aldehydes, ketones and amines were used leading to the expected amino products in moderate to excellent yields. The mechanistic rationale of this reaction has been postulated through the formation of a transient imine species and a diastereoselective version using (R)-phenylethylamine as chiral inducer led to the expected products in moderate to excellent yields and with diastereoselectivities up to 100%.
