Check Digit Verification of cas no

The CAS Registry Mumber 137384-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,8 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137384-89:
(8*1)+(7*3)+(6*7)+(5*3)+(4*8)+(3*4)+(2*8)+(1*9)=155
155 % 10 = 5
So 137384-89-5 is a valid CAS Registry Number.

Intramolecular Acylation of an α-Sulfonyl Anion Generated via Halogen-metal Exchange of an α-Halosulfone Bearing an Unsymmetrical Anhydride

Anderson, M. B.,Lamothe, M.,Fuchs, P. L.

, p. 4457 - 4460 (2007/10/02)

α-Halosulfones are useful for the in situ preparation of α-sulfonyl anions in the presence of acylating agents bearing enolizable protons.Inter- and intramolecular acylations can be effected by halogen-metal exchange at low temperature.
