404875-17-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404875-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,8,7 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 404875-17:
(8*4)+(7*0)+(6*4)+(5*8)+(4*7)+(3*5)+(2*1)+(1*7)=148
148 % 10 = 8
So 404875-17-8 is a valid CAS Registry Number.

Extending distannoxane double ladders using rigid spacers: A double ladder with eight chiral tin atoms- and a twist!

Dakternieks, Dainis,Duthie, Andrew,Zobel, Bernhard,Jurkschat, Klaus,Schürmann, Markus,Tiekink, Edward R.T.

, p. 647 - 652 (2002)

The new bulky silicon-containing ditin precursor p-(RCl2SnCH2SiMe2)2C6H 4 (R = CH2SiMe3 (4)) has been synthesized and further reacted to form a unique double ladder {[p-(R(Cl)SnCH2SiMe2)2C6H4 ]O}4 (6). The two layers within 6 are twisted with respect to one another, resulting in a helical motif and a total absence of molecular symmetry so that there are eight chiral tin atoms within the system. The structure is compared to the double ladder {[m-(R(Cl)SnCH2CH2)2C6H4] O}4 (11), which was prepared from the less sterically demanding ditin precursor m-(RCl2SnCH2CH2)2C6H 4 (10). The two layers within 11 are parallel, and the molecule contains only two kinds of tin atom.
