Check Digit Verification of cas no

The CAS Registry Mumber 1007131-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,7,1,3 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1007131-02:
(9*1)+(8*0)+(7*0)+(6*7)+(5*1)+(4*3)+(3*1)+(2*0)+(1*2)=73
73 % 10 = 3
So 1007131-02-3 is a valid CAS Registry Number.

Zirconium-promoted epoxide rearrangement-alkynylation sequence

Albert, Brian J.,Koide, Kazunori

, p. 1093 - 1098 (2008)

(Chemical Equation Presented) Additions of terminal alkynes to electrophiles are important transformations in organic chemistry. Generally, activated terminal alkynes react with epoxides in an SN2 fashion to form homopropargylic alcohols. We have developed a new synthetic method to form propargylic alcohols from epoxides and terminal alkynes via 1,2-shifts. This method involves cationic zirconium acetylides as both the activator of epoxides and nucleophiles. Due to the mild conditions to pre-activate alkynes with silver nitrate, this synthetic method is useful for both electron-rich and electron-deficient alkynes with other acid- and base-sensitive functional groups.
