The CAS Registry Mumber 148089-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,0,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 148089-33:
(8*1)+(7*4)+(6*8)+(5*0)+(4*8)+(3*9)+(2*3)+(1*3)=152
152 % 10 = 2

Nucleophilic Aromatic Substitution on 1-Alkoxy-2-naphthoates with 1-Naphthyl Grignard Reagents. A Practical and Convenient Asymmetric Synthesis of 1,1'-Binaphthyl-2-carboxylates

Hattori, Tetsutaro,Hotta, Hiroki,Suzuki, Takatsugu,Miyano, Sotaro

, p. 613 - 622 (2007/10/02)

1-Naphthyl Grignard reagents efficiently displace the 1-alkoxyl group of 1-alkoxy-2-naphthoic esters to provide an easy access to the corresponding 1,1'-binaphthyl-2-carboxylates in excellent yields; isopropyl ester is bulky enough to prevent the Grignard
