Check Digit Verification of cas no
The CAS Registry Mumber 62889-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 62889-09:
(7*6)+(6*2)+(5*8)+(4*8)+(3*9)+(2*0)+(1*9)=162
162 % 10 = 2
So 62889-09-2 is a valid CAS Registry Number.

Uebergangsmetallaktivierte organische Verbindungen, IX. Synthese von Polyfuranen durch metallorganische oxidative Kupplung

2,2'- (2a) and 3,3'-bifuran (3), hitherto only accessible by ring-forming syntheses in small yields, and the unknown compounds all-α-terfuran (2b) and all-α-quaterfuran (2c) have been prepared by convenient ring-connecting syntheses in 85, 46, 16, or 53percent-yield, respectively.Lithiation of 2a and subsequent reacting with iodine afforded 5-iodo-2,2'-bifuran (6b, 46percent).According to competition experiments acidity against n-butyllithium is increasing in the sequence furan 2a 2b.
