Check Digit Verification of cas no

The CAS Registry Mumber 1226980-98-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,9,8 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1226980-98:
(9*1)+(8*2)+(7*2)+(6*6)+(5*9)+(4*8)+(3*0)+(2*9)+(1*8)=178
178 % 10 = 8
So 1226980-98-8 is a valid CAS Registry Number.

Stereoselective divergent synthesis of four diastereomers of pachastrissamine (Jaspine B)

supporting information; experimental part, p. 3843 - 3846 (2010/09/03)

Figure presented A divergent short synthesis of four diastereomers of pachastrissamine was achieved. Natural pachastrissamine was synthesized through bis-tosylation of the common intermediate and cyclization. 2-epi- Pachastrissamine was obtained by monotosylation and spontaneous cyclization of d-ribo-phytosphingosine derivative. By use of regio- and stereospecific ring-opening reaction of the orthoester assisted by a Boc group as a key step, 3-epi- and 2,3-epi-pachastrissamines were synthesized. The three stereogenic centers of all the diastereomers were constructed by using Garners aldehyde as the sole chiral source.
