868159-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 868159-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,1,5 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 868159-67:
(8*8)+(7*6)+(6*8)+(5*1)+(4*5)+(3*9)+(2*6)+(1*7)=225
225 % 10 = 5
So 868159-67-5 is a valid CAS Registry Number.

The conversion of pentoses to 3,4-dihydroxyprolines
Taylor, Carol M.,Jones, Chantelle E.,Bopp, Kristin
, p. 9611 - 9617 (2007/10/03)
The synthesis of two naturally-occurring isomers of 3,4-dihydroxyproline is reported. L-2,3-cis-3,4-trans-3,4-Dihydroxyproline was synthesized from L-arabinose in 10 steps and 31% overall yield. The same series of reactions was employed to convert L-xylos
