Check Digit Verification of cas no

The CAS Registry Mumber 309919-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,1 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 309919-01:
(8*3)+(7*0)+(6*9)+(5*9)+(4*1)+(3*9)+(2*0)+(1*1)=155
155 % 10 = 5
So 309919-01-5 is a valid CAS Registry Number.

Practical syntheses of sphingosine-1-phosphate and analogues

Blot, Virginie,Jacquemard, Ulrich,Reissig, Hans-Ulrich,Kleuser, Burkhard

experimental part, p. 759 - 766 (2009/07/19)

Sphingosine-1-phosphate (S1P, 1) is a bioactive sphin- golipid metabolite involved in a variety of critical cellular processes including proliferation, survival, and migration. For this reason the stereoselective syntheses of S1P and analogues are of great interest. Based on L-serine as source of chirality we achieved practical routes to prepare S1P (1) and the aryl group containing analogues 3 and 4 in fair amounts. The crucial stages of the syntheses are: introduction of the required side chain by addition of appropriate organometal- lics to Garner's aldehyde and conversion of the primary alcohols into the corresponding phosphates.
