Check Digit Verification of cas no

The CAS Registry Mumber 122270-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122270-77:
(8*1)+(7*2)+(6*2)+(5*2)+(4*7)+(3*0)+(2*7)+(1*7)=93
93 % 10 = 3
So 122270-77-3 is a valid CAS Registry Number.

A palladadigermetane: Palladium-catalyzed insertion reactions of digermiranes

Tsumuraya, Takeshi,Ando, Wataru

, p. 2286 - 2288 (2008/10/08)

The palladium-catalyzed reactions of digermirane 1 with dimethyl acetylenedicarboxylate and acetylene give the ring expansion products 2 and 3. Reaction with methyl acrylate gives the rearranged product 4. In the stoichiometric reaction of 1 with Pd(PPh3)4, palladadigermetane 6 is isolated as a stable compound. 6 reacts with dimethyl acetylenedicarboxylate, acetylene, and methyl acrylate to yield 2, 3, and 4, respectively. The similar palladium-catalyzed reactions of thia- and selenadigermiranes 9 and 10 with acetylene give the ring expansion products 11 and 12, respectively.
