Check Digit Verification of cas no

The CAS Registry Mumber 188123-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,2 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188123-48:
(8*1)+(7*8)+(6*8)+(5*1)+(4*2)+(3*3)+(2*4)+(1*8)=150
150 % 10 = 0
So 188123-48-0 is a valid CAS Registry Number.

Sterically constrained tricyclic 2-oxazolidinone as excellent chiral auxiliary

Nakamura, Taiju,Hashimoto, Noriaki,Ishizuka, Tadao,Kunieda, Takehisa

, p. 559 - 562 (2007/10/03)

A new class of conformationally rigid 2-oxazolidinones with effectively bulky substituents, derived from the [4+2] cycloadduct of cyclopentadiene and a-oxazolone, serve as extremely powerful chiral auxiliaries for asymmetric alkylations, Diels-Alder reactions and conjugate addition reactions.
