Check Digit Verification of cas no

The CAS Registry Mumber 491593-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,5,9 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 491593-74:
(8*4)+(7*9)+(6*1)+(5*5)+(4*9)+(3*3)+(2*7)+(1*4)=189
189 % 10 = 9
So 491593-74-9 is a valid CAS Registry Number.

3,3-difluoro-1-iodocyclopropenes: A simple synthesis and their reactions

Xu, Wei,Chen, Qing-Yun

, p. 9421 - 9427 (2007/10/03)

The [1 + 2] cycloaddition reaction of 1-iodoalkynes with difluorocarbene, generated from the decomposition of FSO2CF2COOSiMe3 in diglyme in the presence of 10 mol % NaF at 120 °C, gives 3,3-difluoro-1-iodocyclopropenes in good yields. These new iodides can be trifluoromethylated and functionalized via the Heck reaction. The unusual hydrolytic reactions of the iodides under acidic conditions was also investigated.
