24868-59-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24868-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,6 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24868-59:
(7*2)+(6*4)+(5*8)+(4*6)+(3*8)+(2*5)+(1*9)=145
145 % 10 = 5
So 24868-59-5 is a valid CAS Registry Number.

Synthesis and Absolute Configuration of Pyriculol

Suzuki, Masanobu,Sugiyama, Takeyoshi,Watanabe, Masashi,Murayama, Tetsuya,Yamashita, Kyohei

, p. 1121 - 1128 (2007/10/02)

A total synthesis of optically active pyriculol is described.The Wittig reaction between an aldehyde 19 and a triphenylphosphonium ylide 12 gave an intermediate 20.Successive treatment of 20 with p-toluenesulfonic acid, active manganese dioxide, and potassium carbonate gave (3'R,4'S)-pyriculol (23), which was identical with natural pyriculol (1) in all respects.From this synthesis the absolute stereochemistry of pyriculol (1) was determined to be 2--6-hydroxybenzaldehyde.
