Check Digit Verification of cas no

The CAS Registry Mumber 290833-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,3 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 290833-45:
(8*2)+(7*9)+(6*0)+(5*8)+(4*3)+(3*3)+(2*4)+(1*5)=153
153 % 10 = 3
So 290833-45-3 is a valid CAS Registry Number.

Preparation of titanated alkoxyallenes from 3-alkoxy-2-propyn-1-yl carbonates and (η2-propene)Ti(O-i-Pr)2 as an efficient ester homoaldol equivalent

Hanazawa, Takeshi,Okamoto, Sentaro,Sato, Fumie

, p. 2369 - 2371 (2007/10/03)

(equation presented) 3-Alkoxy-2-propyn-1-yl carbonates (2) react with a divalent titanium reagent (η2-propene)Ti(O-i-Pr)2 to afford titanated alkoxyallenes 1 which, in turn, react with aldehydes regiospecifically to provide the corresponding γ-addition products in good to excellent yields, thus affording a convenient method for synthesizing γ-hydroxy esters 3 and/or γ-butyrolactones 4.
