Check Digit Verification of cas no

The CAS Registry Mumber 109467-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,6 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109467-38:
(8*1)+(7*0)+(6*9)+(5*4)+(4*6)+(3*7)+(2*3)+(1*8)=141
141 % 10 = 1
So 109467-38-1 is a valid CAS Registry Number.

Silver(I)-Catalyzed Isomerization of Water-Soluble Quadricyclanes

Maruyama, Kazuhiro,Tamiaki, Hitoshi

, p. 3967 - 3970 (1987)

In aqueous ammonia, silver(I)-catalyzed isomerization of quadricyclanes to norbornadienes was investigated.The catalytic action of silver(I) perchlorate induced rapid and clean isomerization of water-soluble quadricyclanes 1b-g to the corresponding norbornadienes 2b-g even at room temperature.In the isomerization, the silver(I) catalyst might attack 1 from the five-membered ring, which was different from the directions observed in the cobalt(II)-porphyryn- and rhodium(I)-catalyzed reactions.The present reactions proceed via the formation of the cationic species and the successive cleavage of the highly strained cyclopropane ring of 1 to give 2.
