Check Digit Verification of cas no

The CAS Registry Mumber 804565-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,4,5,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 804565-69:
(8*8)+(7*0)+(6*4)+(5*5)+(4*6)+(3*5)+(2*6)+(1*9)=173
173 % 10 = 3
So 804565-69-3 is a valid CAS Registry Number.

Diastereo- and enantio-selective crotylation of α-ketoesters using crotyl boronic acid ester complexes

Chen, Yanping,Eltepu, Laxman,Wentworth Jr., Paul

, p. 8285 - 8288 (2004)

A diastereo- and enantio-selective crotylation of ethyl pyruvate has been achieved using a chiral boronic acid auxiliary-based approach. This reaction creates two contiguous stereogenic centers, one of which is a quaternary carbon with complete diastereoselectivity and with enantioselectivities up to 7:1 (73% ee).
