Check Digit Verification of cas no

The CAS Registry Mumber 105552-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105552-03:
(8*1)+(7*0)+(6*5)+(5*5)+(4*5)+(3*2)+(2*0)+(1*3)=92
92 % 10 = 2
So 105552-03-2 is a valid CAS Registry Number.

ASYMMETRIC INDUCTION BY CHIRAL HETEROCYCLIC COMPOUNDS: REACTION OF CHIRAL N-METHYL-4-PHENYL-1,3-OXAZOLIDINES WITH ORGANOMETALLIC REAGENTS

Takahashi, Hiroshi,Niwa, Hiroyuki,Higashiyama, Kimio

, p. 2099 - 2102 (2007/10/02)

The reaction of (2S,4R)-2-alkyl-N-methyl-4-phenyl-1,3-oxazolidines (1a-c) with Grignard reagent gave (1R,1'R)-form compounds (2a-c) as the major product.On the contrary, the reaction of 1a-c with organotitanium reagent gave (1S,1'R)-form compounds (3a-c) as the major product.This stereoselectivity is a remarkable characteristic of the reaction of 1,3-oxazolidines with organometallic reagents.
