92097-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92097-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,9 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92097-23:
(7*9)+(6*2)+(5*0)+(4*9)+(3*7)+(2*2)+(1*3)=139
139 % 10 = 9
So 92097-23-9 is a valid CAS Registry Number.

Palladium-Catalyzed Conversion of Esters of 4-(Trimethylsilyl)-2-buten-1-ol to Trimethylsilyl Esters. A New Carboxyl Protecting Group
Mastalerz, Harold
, p. 4092 - 4094 (2007/10/02)
Carboxylic acids protected as esters of 4-(trimethylsilyl)-2-buten-1-ol are catalytically converted by Pd(PPh3)4 to trimethylsilyl esters which are readily hydrolyzed by treatment with an alcohol.
