Check Digit Verification of cas no

The CAS Registry Mumber 100340-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 100340-47:
(8*1)+(7*0)+(6*0)+(5*3)+(4*4)+(3*0)+(2*4)+(1*7)=54
54 % 10 = 4
So 100340-47-4 is a valid CAS Registry Number.

New and efficient procedures for the synthesis of stereodefined 2-(hetero) aryl and 2-methyl substituted alkyl 2-alkenoates having very high stereoisomeric purity

Rossi, Renzo

, p. 4495 - 4498 (1992)

Stereodefined 2-(hetero)aryl and 2-methyl substituted alkyl 2-alkenoates of general formulai and2 have been synthesized with a high degree of stereoselectivity as well as in good overall yields starting from alkyl 2-alkynoates,4.

Trisubstituted Olefins via Ester-Derived (Silyloxy)acetylenes: A Highly Stereoselective Alternative to the Horner-Wadsworth-Emmons Reaction

Kowalski, Conrad J.,Sakdarat, Santi

, p. 1977 - 1979 (2007/10/02)

Crude ((triisopropylsilyl)oxy)acetylenes 2, prepared in one step from common esters 1, react with aldehydes in 60-65 percent overall yield after methanol quench to afford α,β-unsaturated esters 3 with very high E/Z stereoselectivity.
