Check Digit Verification of cas no

The CAS Registry Mumber 128038-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,3 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128038-33:
(8*1)+(7*2)+(6*8)+(5*0)+(4*3)+(3*8)+(2*3)+(1*3)=115
115 % 10 = 5
So 128038-33-5 is a valid CAS Registry Number.

Diels-Alder reaction of chiral dienes. Remarkable effect of dienophile polarity upon diastereo face selectivity

Hamada,Sato,Hikota,Yonemitsu

, p. 6405 - 6408 (2007/10/02)

Face selectivity of Diels-Alder reaction of diene having the stereogenic center at allylic position depends on dienophile polarity, and hetero Diels-Alder reaction with dienophile such as N-tosylimine and N-tosylsulfinylimine was found to give exclusively
