Check Digit Verification of cas no

The CAS Registry Mumber 128753-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,5 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128753-04:
(8*1)+(7*2)+(6*8)+(5*7)+(4*5)+(3*3)+(2*0)+(1*4)=138
138 % 10 = 8
So 128753-04-8 is a valid CAS Registry Number.

Reaction of iodonium ylides of 1,3-dicarbonyl compounds with HF reagents

Gondo, Keisuke,Kitamura, Tsugio

, p. 6625 - 6632 (2012)

Reaction of dibenzoylmethane with (diacetoxyiodo)benzene in the presence of KOH in MeCN quantitatively gave the corresponding iodonium ylide, which was treated with a HF reagent to afford the corresponding 2-fluorinated dibenzoylmethane in 14-50% yields.

Transition-metal-free approach to synthesis of indolines from N-(ortho-chloromethyl)aryl amides and iodonium ylides

Huang, Hui,Yang, Yuan,Zhang, Xiaoyun,Zeng, Weilan,Liang, Yun

supporting information, p. 6049 - 6052 (2013/10/22)

A transition-metal-free method for the synthesis of indolines has been developed. In the presence of K2CO3, the cyclization reaction of N-(ortho-chloromethyl)aryl amides and iodonium ylides proceeded smoothly at room temperature in moderate to good yields.
