1239331-78-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1239331-78-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,3,3 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1239331-78:
(9*1)+(8*2)+(7*3)+(6*9)+(5*3)+(4*3)+(3*1)+(2*7)+(1*8)=152
152 % 10 = 2
So 1239331-78-2 is a valid CAS Registry Number.

A convenient synthesis of 2,3-dihydro-3-methylidene-1H-isoindol-1-ones by reaction of 2-formylbenzonitriles with dimethyloxosulfonium methylide

Kobayashi, Kazuhiro,Matsumoto, Kota,Nakamura, Daizo,Fukamachi, Shuhei,Konishi, Hisatoshi

, p. 1048 - 1051 (2010)

A facile method for the synthesis of 2,3-dihydro-3-methylidene-1H-isoindol- 1-one and its derivatives carrying substituent(s) at C(5) and/or C(6) has been developed. The reaction of 2-formylbenzonitrile (1a) with dimethyloxosulfonium methylide, generated by the treatment of trimethylsulfoxonium iodide with NaH in DMSO/THF at 0°, resulted in the formation of 2,3-dihydro-3-methylidene- 1Hisoindol-1-one (2a) in 77% yield. Similarly, six 2-formylbenzonitriles carrying substituent(s) at C(4) and/ or C(5), i.e., 1b - 1g, also gave the corresponding expected products 2b - 2g in comparable yields.
