Check Digit Verification of cas no

The CAS Registry Mumber 132994-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,9 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132994-75:
(8*1)+(7*3)+(6*2)+(5*9)+(4*9)+(3*4)+(2*7)+(1*5)=153
153 % 10 = 3
So 132994-75-3 is a valid CAS Registry Number.

An improved synthesis of N-sulphonyl-1H-azepines under solid-liquid phase-transfer catalysis conditions

Ayyangar,Kumar,Srinivasan

, p. 499 - 502 (2007/10/02)

The synthesis of novel N-sulphonyl-1H-azepines is described starting from arylsulphonyl chlorides in a one-pot operation making use of solid-liquid phase-transfer catalysis technique (benzene/sodium bicarbonate). Good yields were obtained under moderate reaction conditions.
