Check Digit Verification of cas no

The CAS Registry Mumber 22210-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,1 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22210-50:
(7*2)+(6*2)+(5*2)+(4*1)+(3*0)+(2*5)+(1*0)=50
50 % 10 = 0
So 22210-50-0 is a valid CAS Registry Number.

Reaction of Zirconocene Ethylene Complex with Diynes. Formation of Bridged Zirconacyclopentenes

Takahashi, Tamotsu,Kasai, Kayoko,Xi, Zhenfeng,Denisov, Victor

, p. 347 - 348 (1995)

Reactions of diynes RCC-X-CCR with zirconocene ethylene complex Cp2Zr(CH2=CH2) were investigated.When X was C6H4 or C4H2S bridged zirconacyclopentenes were selectively formed.They were easily converted into bridged cyclopentenone derivatives.In the case o
