Check Digit Verification of cas no

The CAS Registry Mumber 15254-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,5 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15254-11:
(7*1)+(6*5)+(5*2)+(4*5)+(3*4)+(2*1)+(1*1)=82
82 % 10 = 2
So 15254-11-2 is a valid CAS Registry Number.

Simple and efficient approach for synthesis of hydrazones from carbonyl compounds and hydrazides catalyzed by meglumine

Zhang, Mo,Shang, Ze-Ren,Li, Xiao-Tang,Zhang, Jia-Nan,Wang, Yong,Li, Kang,Li, Yang-Yang,Zhang, Zhan-Hui

, p. 178 - 187 (2017)

A simple, environmentally benign protocol for synthesis of hydrazones from carbonyl compounds and hydrazides has been developed in the presence of meglumine in aqueous-ethanol media at room temperature. The salient features of the present protocol are mild reaction conditions, short reaction time, high yields, operational simplicity, metal-free, applicability toward large-scale synthesis, and biodegradable and inexpensive catalyst.
