Check Digit Verification of cas no

The CAS Registry Mumber 1204006-30-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,0,0 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1204006-30:
(9*1)+(8*2)+(7*0)+(6*4)+(5*0)+(4*0)+(3*6)+(2*3)+(1*0)=73
73 % 10 = 3
So 1204006-30-3 is a valid CAS Registry Number.

Synthesis of 2-aminobenzoxazoles via copper-catalyzed electrophilic amination of benzoxazoles with O-benzoyl hydroxylamines

Yotphan, Sirilata,Beukeaw, Danupat,Reutrakul, Vichai

, p. 6627 - 6633 (2013/07/26)

An efficient copper-catalyzed electrophilic amination of benzoxazoles with O-benzoyl hydroxylamines is described, employing CuCl catalyst, PPh3 ligand, and LiOtBu base. This simple air-stable copper catalysis enables the preparation of various 2-aminobenzoxazole derivatives at room temperature in good yields.

Silver-mediated direct amination of benzoxazoles: Tuning the amino group source from formamides to parent amines

Cho, Seung Hwan,Kim, Ji Young,Lee, S. Yunmi,Chang, Sukbok

supporting information; experimental part, p. 9127 - 9130 (2010/03/04)

Formamides or parent amines were used as an amino group source for the silver-mediated amination of benzoxazoles. Although reactions with formamides proceeded at high temperatures, the direct amination with amines took place under much milder conditions (
