Check Digit Verification of cas no

The CAS Registry Mumber 756822-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,2 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 756822-62:
(8*7)+(7*5)+(6*6)+(5*8)+(4*2)+(3*2)+(2*6)+(1*2)=195
195 % 10 = 5
So 756822-62-5 is a valid CAS Registry Number.

Acid-catalyzed rearrangement of diaryl hydrazides for the efficient synthesis of functionalized 2,2′-diamino-1,1′-biaryls

Lim, Young-Kwan,Jung, Jin-Woo,Lee, Haiwon,Cho, Cheon-Gyu

, p. 5778 - 5781 (2004)

Diaryl hydrazides prepared from the Pd(0)- or Cu(I)-catalyzed coupling reactions of aryl hydrazides and aryl halides underwent the acid-catalyzed rearrangements to a series of previously unknown 2,2′-diaminobiaryls in good overall yields. The mildness of the reaction conditions allows the presence of various functional groups.
