Check Digit Verification of cas no

The CAS Registry Mumber 202530-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,5,3 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202530-66:
(8*2)+(7*0)+(6*2)+(5*5)+(4*3)+(3*0)+(2*6)+(1*6)=83
83 % 10 = 3
So 202530-66-3 is a valid CAS Registry Number.

Nickel-catalyzed tandem coupling of allyl electrophiles, alkynes, and alkynyltins

Cui, Dong-Mei,Tsuzuki, Takao,Miyake, Kaori,Ikeda, Shin-Ichi,Sato, Yoshiro

, p. 1063 - 1072 (1998)

The nickel-catalyzed intermolecular coupling of allyl acetate or allyl carbonate with alkynes and alkynyltins was carried out in the presence of LiCl to give 3,6-dien-1-yne regio- and stereoselectively. On the other hand, the intramolecular cyclization and coupling of ω-alkynyl electrophiles with alkynyltins gave five-membered cyclic products.
