Check Digit Verification of cas no

The CAS Registry Mumber 502927-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,9,2 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 502927-16:
(8*5)+(7*0)+(6*2)+(5*9)+(4*2)+(3*7)+(2*1)+(1*6)=134
134 % 10 = 4
So 502927-16-4 is a valid CAS Registry Number.

A nucleophilic addition ring closure [NARC]-based synthesis of (+) -nonactic acid

Fraser, Benjamin,Perlmutter, Patrick

, p. 2896 - 2899 (2007/10/03)

Nonactic acid 1 has been synthesized in 12 steps from readily available (S)-(-)-ethyl lactate in 20% overall yield. The key ("NARC") sequence in this method involved anti-aldol addition of acylsultam 3 with aldehyde 4 followed by intramolecular oxymercura
