Check Digit Verification of cas no
The CAS Registry Mumber 131925-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131925-97:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*5)+(2*9)+(1*7)=128
128 % 10 = 8
So 131925-97-8 is a valid CAS Registry Number.

Solid-supported sulfonylhydroxylamine as an effective N-animating agent of anilines
Ohno, Hiroshi,Tanaka, Hiroshi,Takahashi, Takashi
, p. 1191 - 1194 (2007/10/03)
An effective method for the synthesis of aryl hydrazines by amination of anilines using the solid-supported phenylsulfonylhydroxylamine was described. Treatment of aniline with the solid-supported aminating agent, followed by removal of the resin, provided the corresponding hydrazine in 21% yield. The resulting hydrazines were directly adapted to the solid-phase synthesis of indoles, providing nine naltrindole derivatives varying the substituents on the aromatic rings.
