Check Digit Verification of cas no

The CAS Registry Mumber 954113-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,1,1 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 954113-53:
(8*9)+(7*5)+(6*4)+(5*1)+(4*1)+(3*3)+(2*5)+(1*3)=162
162 % 10 = 2
So 954113-53-2 is a valid CAS Registry Number.

Further explorations on bridged 1,2,4-trioxanes

Zhang, Qi,Wu, Yikang

, p. 10189 - 10201 (2007)

Three new bicyclo[3.2.1]-type 1,2,4-trioxanes have been designed and synthesized. One of them demonstrates better tolerance of the intramolecular hemiketals to steric crowding in hydroperoxidation. The other represents a prototype for possible manipulation of the transient radicals generated in cleavage reactions. A new substitution pattern in the bridged system is explored through synthesis of the third molecule. The configurations of all stereogenic centers in the bridged system can be effectively controlled by the chirality of the allyl alcohol as illustrated by the enantioselective synthesis of the fourth molecule. Finally, similar bicyclo[3.3.1]-type 1,2,4-trioxanes are shown very difficult to be synthesized because of the involvement of a conformer with two substituents at axial positions at the same time.
