Check Digit Verification of cas no

The CAS Registry Mumber 343922-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,9,2 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 343922-11:
(8*3)+(7*4)+(6*3)+(5*9)+(4*2)+(3*2)+(2*1)+(1*1)=132
132 % 10 = 2
So 343922-11-2 is a valid CAS Registry Number.

Diisobutylaluminium-promoted regioselective de-O-methylation of cyclodextrins: An expeditious entry to selectively modified cyclodextrins

Wang, Wei,Pearce, Alan J.,Zhang, Yongmin,Sinay, Pierre

, p. 517 - 523 (2001)

Substituted cyclodextrins carrying methyl groups on the primary rim undergo highly regioselective de-O-methylation in the presence of benzyl groups, using diisobutylaluminium. This gave access to AD or AB di-6-O-demethylated derivatives, which were fully
