Check Digit Verification of cas no

The CAS Registry Mumber 1356917-97-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,9,1 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1356917-97:
(9*1)+(8*3)+(7*5)+(6*6)+(5*9)+(4*1)+(3*7)+(2*9)+(1*7)=199
199 % 10 = 9
So 1356917-97-9 is a valid CAS Registry Number.

Highly enantioselective synthesis of silahelicenes using Ir-catalyzed [2+2+2] cycloaddition

Shibata, Takanori,Uchiyama, Toshifumi,Yoshinami, Yusuke,Takayasu, Satoshi,Tsuchikama, Kyoji,Endo, Kohei

, p. 1311 - 1313 (2012/02/16)

Silahelicenes, which contain two silole moieties in a helically chiral structure, were synthesized by a chiral Ir-catalyzed intermolecular [2+2+2] cycloaddition of tetraynes with diynes along with a Ni-mediated intramolecular [2+2+2] cycloaddition. The photophysical properties of the obtained highly enantiomerically enriched silahelicenes (up to 93% ee) were also measured. The Royal Society of Chemistry 2012.
