Check Digit Verification of cas no
The CAS Registry Mumber 91348-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,4 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91348-21:
(7*9)+(6*1)+(5*3)+(4*4)+(3*8)+(2*2)+(1*1)=129
129 % 10 = 9
So 91348-21-9 is a valid CAS Registry Number.

Gold-catalyzed oxidative ring expansions and ring cleavages of alkynylcyclopropanes by intermolecular reactions oxidized by diphenylsulfoxide

supporting information; experimental part, p. 9891 - 9894 (2011/02/24)
A golden opportunity: A novel gold-catalyzed oxidative ring-expansion of unactivated cyclopropylalkynes using Ph2SO has been developed (see scheme). For substrates bearing a donor group at the cyclopropane ring, preliminary results reveal a distinct cleavage of the cyclopropane unit; such a ring cleavage is further applicable to the synthesis of 2H-pyrans.

An improved synthesis of cyclopropanes from homoallenic alcohols
Pyo, Sungsoo,Skowron III, Joseph F.,Cha, Jin K.
, p. 4703 - 4706 (2007/10/02)
Treatment of the readily available β-allene tosylates with LDA or nBuLi provides an expeditious, although stereorandom, synthesis of functionalized cyclopropanes which can be easily prepared in high enantiomeric purity.
