Check Digit Verification of cas no

The CAS Registry Mumber 336182-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,6,1,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 336182-90:
(8*3)+(7*3)+(6*6)+(5*1)+(4*8)+(3*2)+(2*9)+(1*0)=142
142 % 10 = 2
So 336182-90-2 is a valid CAS Registry Number.

Ester derived titanium enolate aldol reaction: Chelation controlled diastereoselective synthesis of syn-aldols

Ghosh, Arun K.,Kim, Jae-Hun

, p. 1227 - 1231 (2007/10/03)

A chelation controlled and highly diastereoselective synthesis of syn-aldols is described. Aldol reaction of commercially available L-phenylalaninol derived esters with a variety of bidentate oxyaldehydes proceeded with excellent syn-diastereoselectivities and isolated yields.
