Check Digit Verification of cas no

The CAS Registry Mumber 129548-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,4 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129548-02:
(8*1)+(7*2)+(6*9)+(5*5)+(4*4)+(3*8)+(2*0)+(1*2)=143
143 % 10 = 3
So 129548-02-3 is a valid CAS Registry Number.

Stereoselective aldol reactions of β-chlorovinyl ketones using dienol borinates: A new synthesis of dihydropyrones

Paterson, Ian,Osborne, Simon

, p. 2213 - 2216 (2007/10/02)

The syn-selective aldol reaction of β-chlorovinyl ketones using dienol borinates can be coupled with a trimethylsilyltriflate promoted cyclisation to give cis-dihydropyrones, 4 6 7. Use of dienol diisopinoeampheylborinates leads to an enantioselective synthesis of dihydropyrones.
