Check Digit Verification of cas no
The CAS Registry Mumber 823-91-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 823-91:
(5*8)+(4*2)+(3*3)+(2*9)+(1*1)=76
76 % 10 = 6
So 823-91-6 is a valid CAS Registry Number.

Acetylation of trimethylsilyl bicyclo(n,1,0)alkanes was studied using the CH3COCl/AlCl3 complex.The results showed that both larger cycle size (n = 3, 4 or 6) and stereochemistry of the substrate (SiMe3 group in endo or exo position) played a prominent role in the orientation of the reaction : depending upon the starting products, either bicyclic or ethylenic and/or chloro ketones were formed.The results can be rationalized in terms of steric hindrance considerations.They allowed us to propose a new convenient synthesis of acetyl bicyclo(n,1,0)alkanes and also of 1-acetyl 2-cyclohexene.
