Check Digit Verification of cas no

The CAS Registry Mumber 853015-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,0,1 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 853015-01:
(8*8)+(7*5)+(6*3)+(5*0)+(4*1)+(3*5)+(2*0)+(1*1)=137
137 % 10 = 7
So 853015-01-7 is a valid CAS Registry Number.

A convenient synthesis of immunosuppressive agent FTY720 using the petasis reaction

Sugiyama, Shigeo,Arai, Satoshi,Kiriyama, Matsuri,Ishii, Keitaro

, p. 100 - 102 (2007/10/03)

A convenient synthesis of immunosuppressive agent FTY720 (1) using the Petasis reaction was developed. 4-Octylbenzaldehyde (9) was converted into 1-ethenyl-4-octylbenzene (11) by two-step synthesis. Hydroboration of 11 using catecholborane and hydrolysis gave (E)-2-(4-octylphenyl)vinylboronic acid (4). The Petasis reaction of 4, dihydroxyacetone (3), and benzylamine following catalytic hydrogenation afforded FTY720 (1).
