Check Digit Verification of cas no
The CAS Registry Mumber 1267969-05-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,9,6 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1267969-05:
(9*1)+(8*2)+(7*6)+(6*7)+(5*9)+(4*6)+(3*9)+(2*0)+(1*5)=210
210 % 10 = 0
So 1267969-05-0 is a valid CAS Registry Number.

Cycloisomerization of bifunctionalized allenes: Synthesis of 3(2h)-furanones in water
Poonoth, Manojkumar,Krause, Norbert
, p. 1934 - 1936 (2011)
A simple protocol for the efficient synthesis of 3(2H)-furanones by cycloisomerization of allenic hydroxyketones is described. This transformation is achieved in water and in the absence of any expensive metal catalysts.
