Check Digit Verification of cas no

The CAS Registry Mumber 78765-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,6 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78765-64:
(7*7)+(6*8)+(5*7)+(4*6)+(3*5)+(2*6)+(1*4)=187
187 % 10 = 7
So 78765-64-7 is a valid CAS Registry Number.

Novel synthesis of some isatin hydrazones and pyridazinophthalazines

Abou-Elmagd, Wael S.I.,Hashem, Ahmed I.

, p. 1083 - 1091 (2013)

The acid hydrazides bearing furyl, pyrazolyl, and indolyl rings 2 condense with isatin to give the corresponding hydrazones 3. Ring closure of the latter in an HCl=AcOH mixture led to the construction of a new pyrrolinone ring 4. The hydrazides 2 condensed also with phthalic anhydride to give the corresponding pyridazinophthalazines 5.
