Check Digit Verification of cas no

The CAS Registry Mumber 103559-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,5 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103559-17:
(8*1)+(7*0)+(6*3)+(5*5)+(4*5)+(3*9)+(2*1)+(1*7)=107
107 % 10 = 7
So 103559-17-7 is a valid CAS Registry Number.

Reaction of trimethylsilanes with Arenes and Alk-1-enes in the Presence of Lewis Acid: Syntheses of - and (1-Arylthioalk-3-enyl)-trimethylsilanes

Ishibashi, Hiroyuki,Nakatani, Hiroshi,Umei, Yoshizumi,Yamamoto, Wako,Ikeda, Masazumi

, p. 589 - 594 (2007/10/02)

Treatment of equimolar amounts of the trimethylsilanes (2) or (3) and electron-rich arenes with an equimolar amount of Lewis acid (SnCl4 or TiCl4) gave the Friedel-Crafts reaction products, trimethylsilanes (4) or (5), in high yields.Similar treatment of the chlorides (2) or (3) with alk-1-enes gave ene type products, trimethylsilanes (12) or (13), in moderate yields.Some chemical transformations of these products are also described.

INTRODUCTION OF AN ARYLTHIO(TRIMETHYLSILYL)METHYL GROUP INTO ARENES BY FRIEDEL-CRAFTS REACTION: SYNTHESIS OF ARYLMETHYLTRIMETHYLSILANES

Ishibashi, Hiroyuki,Nakatani, Hiroshi,Umei, Yoshizumi,Ikeda, Masazumi

, p. 4373 - 4374 (2007/10/02)

Friedel-Crafts reactions of trimethylsilanes (1a, b) with arenes gave trimethylsilanes (2a,b), which were converted into arylmethyltrimethylsilanes (3) by reduction with Raney nickel.
