Check Digit Verification of cas no

The CAS Registry Mumber 17798-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,9 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17798-86:
(7*1)+(6*7)+(5*7)+(4*9)+(3*8)+(2*8)+(1*6)=166
166 % 10 = 6
So 17798-86-6 is a valid CAS Registry Number.

Halogen cation induced stereoselective semipinacol-type rearrangement of allylic alcohols: A highly efficient approach to α-quaternary β-haloketo compounds

Wang, Bao Min,Song, Zhen Lei,Fan, Chun An,Tu, Yong Qiang,Chen, Wei Ming

, p. 1497 - 1499 (2007/10/03)

Allylic alcohols were found to undergo a semipinacol-type rearrangement induced by halogen cation generated from the chloramine-T/ZnX2 combination, which provided a highly efficient and stereoselective method for the preparation of α-quaternary β-haloketo compounds. This reaction is valuable and versatile since a quaternary carbon could be constructed effectively and three kinds of β-haloketo compounds (X = Cl, Br, I) could be achieved readily.
