4201-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4201-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4201-57:
(6*4)+(5*2)+(4*0)+(3*1)+(2*5)+(1*7)=54
54 % 10 = 4
So 4201-57-4 is a valid CAS Registry Number.

A Convenient Synthesis of Galactocerebroside Using D-Glucosamine as a Chiral Source of the Ceramide Moiety
Murakami, Teiichi,Minamikawa, Hiroyuki,Hato, Masakatsu
, p. 1875 - 1876 (2007/10/02)
Galactocerebroside has been efficiently synthesized in 11 steps starting from N-benzoyl-D-glucosamine via 3-O-benzoylceramide with minimal manipulations of protecting groups.
