Check Digit Verification of cas no

The CAS Registry Mumber 82959-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82959-89:
(7*8)+(6*2)+(5*9)+(4*5)+(3*9)+(2*8)+(1*9)=185
185 % 10 = 5
So 82959-89-5 is a valid CAS Registry Number.

A NEW TRIMETHYLSILYL TRIFLATE-CATALYZED 1,3-DIPOLAR CYCLOADDITION LEADING TO PYRROLIDINES

Achiwa, Kazuo,Sekiya, Minoru

, p. 2589 - 2592 (1982)

Pyrrolidines were obtained by a new, trimethylsilyl triflate-catalyzed cycloaddition of an intermediary N-trimethylsilylated methylene-iminium ylide, a 1,3 dipole, to olefinic and acetylenic dipolarophiles.

Trimethylsilyl Triflate-Catalyzed 1,3-Dipolar Cycloaddition Leading to N-Unsubstituted Pyrrolidines

Achiwa, Kazuo,Sugiyama, Kaori,Sekiya, Minoru

, p. 1975 - 1981 (2007/10/02)

Dipolar cycloaddition of an intermediary N-trimethylsilyltrimethylsilylmethyliminium salt formed from N-(benzylidene)trimethylsilylmethylamine by the catalytical action of trimethylsilyl triflate to conjugated alkene or alkyne gave N-unsubstituted pyrroli
