Check Digit Verification of cas no
The CAS Registry Mumber 143262-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,6 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143262-21:
(8*1)+(7*4)+(6*3)+(5*2)+(4*6)+(3*2)+(2*2)+(1*1)=99
99 % 10 = 9
So 143262-21-9 is a valid CAS Registry Number.

DIRECTED LITHIATION OF 1-(tert-BUTOXYCARBONYL)INDOLINES. A CONVENIENT ROUTE TO 7-SUBSTITUTED INDOLINES
Iwao, Masatomo,Kuraishi, Tsukasa
, p. 1031 - 1038 (2007/10/02)
1-(tert-Butoxycarbonyl)indolines were regioselectively lithiated at 7-position with s-BuLi-TMEDA in ether or THF at -78 deg C.The lithiated species were reacted with a range of electrophiles to give 7-substituted indoline derivatives.
