350795-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 350795-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,7,9 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 350795-03:
(8*3)+(7*5)+(6*0)+(5*7)+(4*9)+(3*5)+(2*0)+(1*3)=148
148 % 10 = 8
So 350795-03-8 is a valid CAS Registry Number.

Practical synthesis of chiral emopamil left hand as a bioactive motif.

, p. 6228 - 6231 (2002)

An asymmetric synthesis of (2S)-2-(2-isopropyl)-5-hydroxy-2-phenylpentanenitrile (emopamil left hand, 2) has been completed by use of the MAD (methyl aluminum bis(4-methyl-2,6-di-tert-butylphenoxide)-induced rearrangement of a chiral epoxyalcohol as the key reaction. The stereochemistry of the chiral quaternary center was confirmed by transformation of 2 to (S)-noremopamil. This method requires minimal purification procedures and affords high chemical and optical yields. Acid-catalyzed isomerization of an allylaldehyde and retro-aldol type racemization at the quaternary carbon of a nitrile-alcohol were encountered.
