159846-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159846-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,4 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 159846-98:
(8*1)+(7*5)+(6*9)+(5*8)+(4*4)+(3*6)+(2*9)+(1*8)=197
197 % 10 = 7
So 159846-98-7 is a valid CAS Registry Number.

Periplanone Total Synthesis via Intramolecular Pinacol Coupling
McMurry, John E.,Siemers, Nathan O.
, p. 4505 - 4508 (2007/10/02)
We have carried out an enantioselective synthesis of (-)-periplanone C by a route involving titanium-induced, intramolecular pinacol coupling reaction of 1,10 keto aldehyde as the key step.The coupling occurs with predictable stereochemistry to give a mix
