Check Digit Verification of cas no

The CAS Registry Mumber 136559-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136559-22:
(8*1)+(7*3)+(6*6)+(5*5)+(4*5)+(3*9)+(2*2)+(1*2)=143
143 % 10 = 3
So 136559-22-3 is a valid CAS Registry Number.

Stereoselective Synthesis of Meta- and Three-bridged Cyclophanes with Intramolecular Photocycloaddition by Using the Steric Effect of Methoxyl Group

Okada, Yukihiro,Ishii, Fuyuhiko,Kasai, Yoshinori,Nishimura, Jun

, p. 12159 - 12184 (2007/10/02)

Key Words: Cyclophane; stereoselectivity; conformation; regioisomer; photocycloaddition; torsional angle.Dimethoxymetacyclophanes 9 (n=2,3,4,5, and 6) and 10 were stereoselectively obtained in 61-87percent yields by means of photocycloaddition.

Synthesis and Structural Analysis of Dimethoxymetacyclophanes

Okada, Yukihiro,Mabuchi, Shunsuke,Kurahayashi, Masaki,Nishimura, Jun

, p. 1345 - 1348 (2007/10/02)

Dimethoxymetacyclophanes were obtained in 46-68percent yields through photocycloaddition of corresponding styrene derivatives.These metacyclophanes were assigned to be of syn-conformation (n=3,4,5, and 6) or the mixture of syn- and anti-conform
