74671-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74671-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,7 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74671-50:
(7*7)+(6*4)+(5*6)+(4*7)+(3*1)+(2*5)+(1*0)=144
144 % 10 = 4
So 74671-50-4 is a valid CAS Registry Number.

, p. 368 - 372 (2007/10/02)
2-Amino-3-(ω-phthalimidoalkyl)indoles have been obtained by the rearrangement of ω-phthalimido acid β-phenylhydrazides under the action of POCl3.The possibility has been studied of eliminating the phthalyl protective group from these compounds and a conve
