Check Digit Verification of cas no

The CAS Registry Mumber 544476-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,4,4,7 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 544476-92:
(8*5)+(7*4)+(6*4)+(5*4)+(4*7)+(3*6)+(2*9)+(1*2)=178
178 % 10 = 8
So 544476-92-8 is a valid CAS Registry Number.

Synthesis of fluorescence-labeled sphingosine and sphingosine 1-phosphate; Effective tools for sphingosine and sphingosine 1-phosphate behavior

, p. 661 - 664 (2007/10/03)

A fluorescence-labeled sphingosine and sphingosine 1-phosphate have been successfully synthesized from the oxazolidinone methyl ester derived from glycidol via monoalkylation and the stereoselective reduction of the resulting ketone. The labeled sphingosine was converted into its phosphate by treatment with sphingosine kinase 1 (SPHK1) from mouse, and in platelets, and it was incorporated into the Chinese Hamster Ovarian (CHO) cells. In addition, MAPK was activated by NBD-Sph-1-P through Edg-1, Sph-1-P receptor.
