172373-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172373-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,3,7 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 172373-87:
(8*1)+(7*7)+(6*2)+(5*3)+(4*7)+(3*3)+(2*8)+(1*7)=144
144 % 10 = 4
So 172373-87-4 is a valid CAS Registry Number.

Formal synthesis of (±)-upial. Oxidative free-radical cyclization of unsaturated 1,3-cyclohexanediones
Snider, Barry B.,O'Neil, Steven V.
, p. 12983 - 12994 (2007/10/02)
Oxidative free-radical cyclization of 4-(3-hexenyl)-1,3-cyclohexanedione 8 affords 85% of a mixture of 7 and 29. Short sequences were developed to convert this mixture to 2, a late intermediate in Taschner's synthesis of upial.
