Check Digit Verification of cas no

The CAS Registry Mumber 852249-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,2,4 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 852249-82:
(8*8)+(7*5)+(6*2)+(5*2)+(4*4)+(3*9)+(2*8)+(1*2)=182
182 % 10 = 2
So 852249-82-2 is a valid CAS Registry Number.

Synthesis of new chiral hydroxy oxazolines and their use in the catalytic asymmetric phenyl transfer to aldehydes

Bolm, Carsten,Schmidt, Frank,Zani, Lorenzo

, p. 1367 - 1376 (2007/10/03)

Starting either from benzoylformic acid or ethyl oxamate and enantiopure β-amino alcohols, several chiral α-hydroxy oxazolines have been prepared by short synthetic routes. Subsequently, they have been employed in the catalytic asymmetric phenyl transfer to various aldehydes, using a mixture of triphenylborane and diethylzinc as the phenyl source. The corresponding secondary alcohols were obtained with good enantioselectivities (up to 81% ee) and up to 92% yield.
