Check Digit Verification of cas no

The CAS Registry Mumber 58838-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,3 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58838-09:
(7*5)+(6*8)+(5*8)+(4*3)+(3*8)+(2*0)+(1*9)=168
168 % 10 = 8
So 58838-09-8 is a valid CAS Registry Number.

Improved protocol for Thorpe reaction: Synthesis of 4-amino-1-arylpyrazole using solid-liquid phase-transfer conditions

Desai, Nirmal D.,Shah, Rina D.

, p. 316 - 327 (2008/09/16)

Solid-liquid phase-transfer conditions were employed for the first time in the Thorpe reaction to synthesize 4-amino-1-aryl-3,5-substituted-1H-pyrazoles 3. Aryl amines were diazotized and coupled with various active methylene compounds such as cyano aceta
