Check Digit Verification of cas no

The CAS Registry Mumber 1365543-21-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,5,5,4 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1365543-21:
(9*1)+(8*3)+(7*6)+(6*5)+(5*5)+(4*4)+(3*3)+(2*2)+(1*1)=160
160 % 10 = 0
So 1365543-21-0 is a valid CAS Registry Number.

Mechanism and optimisation of the homoboroproline bifunctional catalytic asymmetric aldol reaction: Lewis acid tuning through in situ esterification

Georgiou, Irene,Whiting, Andrew

, p. 2422 - 2430 (2012)

The use of homoboroproline as a bifunctional catalyst in the asymmetric aldol reaction has been investigated mechanistically, particularly with respect to tuning the Lewis acidity of boron by in situ esterification with mildly sigma-electron withdrawing diols such as hydrobenzoin and tartrate esters. The stability of simple cyclohexyl and cyclopentyl boronate diol esters shows that the 5-ring boronate esters are more stable, which sheds light on the mode of action of esterified homoboroproline catalyst in the enamine-mediated aldol reaction, which is also studied by NMR. The result is reaction optimisation to provide an efficient aldol reaction and a proposed mechanistic proposal. The Royal Society of Chemistry 2012.
