114273-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114273-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,2,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114273-31:
(8*1)+(7*1)+(6*4)+(5*2)+(4*7)+(3*3)+(2*3)+(1*1)=93
93 % 10 = 3
So 114273-31-3 is a valid CAS Registry Number.

Total Synthesis of (-)-Specionin
Whitesell, James K.,Allen, Diane, E.
, p. 3583 - 3588 (2007/10/02)
The stereochemically discriminating, kinetic selection between the enantiotopically related alkene units in diene 3 was used to establish the absolute stereochemistry of the natural product specionin.Thus, reaction of 3 with glyoxylate 4R afforded the ene
