219646-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219646-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,4 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219646-77:
(8*2)+(7*1)+(6*9)+(5*6)+(4*4)+(3*6)+(2*7)+(1*7)=162
162 % 10 = 2
So 219646-77-2 is a valid CAS Registry Number.

Synthesis of cyclic sphingosine 1,3-phosphate (cSPP) through a photolytic reaction
Qiao, Lixin,Kozikowski, Alan P.
, p. 8959 - 8962 (2007/10/03)
The synthesis of cyclic sphingosine 1,3-phosphate through photolytic methodology is described starting from D-erythro-sphingosine. A bifunctional phosphorylating reagent, 2-cyanoethyl N,N-diisopropylchlorophosphoramidite, is used to introduce the cyclic 1
