Check Digit Verification of cas no

The CAS Registry Mumber 186002-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,0,0 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 186002-85:
(8*1)+(7*8)+(6*6)+(5*0)+(4*0)+(3*2)+(2*8)+(1*5)=127
127 % 10 = 7
So 186002-85-7 is a valid CAS Registry Number.

Bicyclization of enynes using the Cp2TiCl2-Mg-BTC system: A practical method to bicyclic cyclopentenones

Zhao, Zongbao,Ding, Yu,Zhao, Gang

, p. 9285 - 9291 (1998)

Bicyclic titanacycles 2 generated with the Cp2TiCl2-Mg-P(OEt)3 system can be trapped with bis(trichloromethyl) carbonate (BTC) to give bicyclic cyclopentenones 3 in good yields. The titanacycle 2m was isolated and well- identified. Bicyclization of enynes containing 1,2-disubstituted olefin by this method gave good results with excellent stereoselectivity.

Atom-Economical Ni-Catalyzed Diborylative Cyclization of Enynes: Preparation of Unsymmetrical Diboronates

Cabrera-Lobera, Natalia,Quirós, M. Teresa,Brennessel, William W.,Neidig, Michael L.,Bu?uel, Elena,Cárdenas, Diego J.

supporting information, p. 6552 - 6556 (2019/08/20)

We report a Ni-catalyzed diborylative cyclization of enynes that affords carbo- and heterocycles containing both alkyl- and alkenylboronates. The reaction is fully atom-economical, shows a broad scope, and employs a powerful and inexpensive catalytic Ni-b
