Check Digit Verification of cas no
The CAS Registry Mumber 411230-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,1,2,3 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 411230-53:
(8*4)+(7*1)+(6*1)+(5*2)+(4*3)+(3*0)+(2*5)+(1*3)=80
80 % 10 = 0
So 411230-53-0 is a valid CAS Registry Number.

A concise route to D-erythro-sphingosine from N-Boc-L-serine derivatives via sulfoxide or sulfone intermediates
Chun, Jiong,Li, Guoqing,Byun, Hoe-Sup,Bittman, Robert
, p. 375 - 377 (2007/10/03)
Sulfoxide and sulfone intermediates 7 and 15, respectively, were employed to synthesize synthons 3 and 4, which are readily converted to the naturally occurring (2S,3R,4(E))-sphingosine 1 and (2S,3R)-sphinganine 2.
