Check Digit Verification of cas no

The CAS Registry Mumber 129512-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,1 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129512-44:
(8*1)+(7*2)+(6*9)+(5*5)+(4*1)+(3*2)+(2*4)+(1*4)=123
123 % 10 = 3
So 129512-44-3 is a valid CAS Registry Number.

Tert-Butyldimethylsilyl Amine (TBDMS-NH2): A Mild and Green Reagent for the Protection of Benzyl Alcohols, Phenols, and Carboxylic Acids under Solvent-Free Conditions

Duczynski, Jeremy A.,Fuller, Rebecca,Stewart, Scott G.

, p. 1172 - 1179 (2016/10/13)

Herein, we present the use of the tert-butyldimethylsilyl amine (TBDMS-NH2) as a silylating reagent for phenols, benzyl alcohols, and carboxylic acids. Unlike other silyl protection reactions, this reported process with TBDMS-NH2 does not involve the form

Photooxygenation of 3- and 2-silyloxybenzofurans: Rearrangement of dioxetanes via α-silylperoxy ketones to ketoester cleavage products

Adam,Kades,Wang

, p. 2259 - 2262 (2007/10/02)

Photooxygenation of 2-methyl-3-silyloxybenzofurans 1 afforded isolable dioxetranes 2, the latter rearranged via α-silylperoxy ketones 3 to cleavage products 4; 2-silyloxy-3-methylbenzofuran 6 with 1O2 gave the more stable dioxetane 7.
