128459-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128459-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,5 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128459-28:
(8*1)+(7*2)+(6*8)+(5*4)+(4*5)+(3*9)+(2*2)+(1*8)=149
149 % 10 = 9
So 128459-28-9 is a valid CAS Registry Number.

Efficient and systematic syntheses of enantiomerically pure and regiospecifically protected myo-inositols

Bruzik, Karol S.,Tsai, Ming-Daw

, p. 6361 - 6374 (2007/10/02)

Efficient and systematic syntheses of a variety of enantiomerically pure and regiospecifically protected myo-inositols, which can be readily used as precursors for most natural and unnatural derivatives of myo-inositol, have been developed. The key strate

Synthesis of the enantiomeric 1,4,5,6-tetra-O-benzyl-myo inositols

Bruzik, Karol S.,Salamonczyk, Grzegorz M.

, p. 67 - 73 (2007/10/02)

The synthesis of the optically pure 1,4,5,6-tetra-O-benzyl-myo-inositols was achieved in four steps via diastereomeric 2,3-spiro-acetals of myo-inositol with l- and d-camphor as the key intermediates. Camphor dimethyl acetal was used for the acetalation r
