Check Digit Verification of cas no

The CAS Registry Mumber 205371-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,3,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205371-69:
(8*2)+(7*0)+(6*5)+(5*3)+(4*7)+(3*1)+(2*6)+(1*9)=113
113 % 10 = 3
So 205371-69-3 is a valid CAS Registry Number.

Synthesis of all stereoisomers of KRN7000, the CD1d-binding NKT cell ligand

Park, Jeong-Ju,Lee, Ji Hyung,Ghosh, Subhash C.,Bricard, Gabriel,Venkataswamy, Manjunatha M.,Porcelli, Steven A.,Chung, Sung-Kee

scheme or table, p. 3906 - 3909 (2009/04/06)

KRN7000 is an important ligand identified for CD1d protein of APC, and KRN7000/CD1d complex can stimulate NKT cells to release Th1 and Th2 cytokines. In an effort to understand the structure-activity relationships, we have carried out the synthesis of a c

Practical synthesis of KRN7000 from phytosphingosine

Kim, Sanghee,Song, Soyoung,Lee, Taeho,Jung, Sungkyu,Kim, Deukjoon

, p. 847 - 850 (2007/10/03)

The efficient and practical synthesis of die biologically important a-galactosylceramides, KRN7000, from phytosphingosine has been achieved in six steps in high overall yield.

Diastereoselective epoxidation of the double bond at C-4 of sphingosines to provide phytosphingosine relatives such as α-galactosylceramide KRN7000

Takikawa, Hirosato,Muto, Shin-etsu,Mori, Kenji

, p. 3141 - 3150 (2007/10/03)

Diastereoselective epoxidation of the double bond at C-4 of two sphingosine derivatives [3, R = (CH2)7Me or (CH2)12Me] was studied. Dimethyldioxirane was found to be the best oxidant for that purpose. Application of this epoxidation resulted in a new synthesis of the α- galactosylceramide KRN7000 (2), which has an enhancing effect on the activity of natural killer cells.
