Check Digit Verification of cas no

The CAS Registry Mumber 942268-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,2,6 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 942268-03:
(8*9)+(7*4)+(6*2)+(5*2)+(4*6)+(3*8)+(2*0)+(1*3)=173
173 % 10 = 3
So 942268-03-3 is a valid CAS Registry Number.

Synthesis of pyroglutamic acid derivatives via double michael reactions of alkynones

Scansetti, Myriam,Hu, Xiangping,McDermott, Benjamin P.,Lam, Hon Wai

, p. 2159 - 2162 (2008/02/02)

In the presence of substoichiometric quantities of potassium tert-butoxide and an additional metal salt, amide-tethered diacids undergo double Michael reactions with alkynones to provide highly functionalized pyroglutamic acid derivatives. The metal salt was found to play an important role in improving the diastereoselectivities of the reactions.
