Check Digit Verification of cas no

The CAS Registry Mumber 960005-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,6,0,0,0 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 960005-34:
(8*9)+(7*6)+(6*0)+(5*0)+(4*0)+(3*5)+(2*3)+(1*4)=139
139 % 10 = 9
So 960005-34-9 is a valid CAS Registry Number.

NOVEL ALPHA-FLUOROMETHOXYCARBOXYLIC ESTER, PROCESS FOR PRODUCING THE ALPHA-FLUOROMETHOXYCARBOXYLIC ESTER, AND PROCESS FOR PRODUCING SEVOFLURANE

-

Page/Page column 4-5, (2010/02/17)

The present invention provides a novel α-fluoromethoxycarboxylic ester represented by Formula (1): (CF3)2C(OCH2F)COOR wherein R is a hydrocarbon group that may have a substituent; a process for producing 1,1,1,3,3,3-hexafluoroisopropyl fluoromethyl ether, the process including hydrolyzing and decarboxylating the α-fluoromethoxycarboxylic ester; and a process for producing an α-fluoromethoxycarboxylic ester represented by Formula (1): (CF3)2C (OCH2F)COOR, the process including reacting an α-hydroxycarboxylic ester represented by Formula (2): (CF3)2C(OH)COOR with a halofluoromethane in the presence of an alkaline compound. According to the present invention, 1,1,1,3,3,3-hexafluoroisopropyl fluoromethyl ether (sevoflurane), which is known as an anesthetic compound, can be efficiently produced at low cost.
