Check Digit Verification of cas no

The CAS Registry Mumber 1089199-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,1,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1089199-05:
(9*1)+(8*0)+(7*8)+(6*9)+(5*1)+(4*9)+(3*9)+(2*0)+(1*5)=192
192 % 10 = 2
So 1089199-05-2 is a valid CAS Registry Number.

Competition of substituents for ortho direction of metalation of veratric acid

Chau, Nguyet Trang Thanh,Nguyen, Thi Huu,Castanet, Anne-Sophie,Nguyen, Kim Phi Phung,Mortier, Jacques

, p. 10552 - 10557 (2008)

LTMP (5 equiv) metalates randomly veratric acid (1). Under external quench conditions, the thermodynamically more stable lithium 2-lithio-3,4-dimethoxybenzoate (2) reacts with a variety of electrophiles to give versatile building units that are not easily accessible by conventional means. Under in situ quench conditions (LTMP/TMSCl), a reversal of regioselectivity is observed and 6-trimethylsilyl-3,4-dimethoxybenzoic acid (10) is formed predominantly.
