Check Digit Verification of cas no

The CAS Registry Mumber 1384521-02-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,5,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1384521-02:
(9*1)+(8*3)+(7*8)+(6*4)+(5*5)+(4*2)+(3*1)+(2*0)+(1*2)=151
151 % 10 = 1
So 1384521-02-1 is a valid CAS Registry Number.

Synthesis of Oxindole Derivatives via Intramolecular C–H Insertion of Diazoamides Using Ru(II)-Pheox Catalyst

Phan Thi Thanh, Nga,Dang Thi Thu, Huong,Tone, Masaya,Inoue, Hayato,Iwasa, Seiji

, (2020/10/02)

This work presented the efficient intramolecular aromatic C–H insertion of diazoacetamide. The 1a–1o diazo compounds (except for 1k) were converted into their corresponding oxindoles via an intramolecular C–H insertion reaction in the presence of a Ru catalyst. The Ru-Pheox catalyst was shown to be highly efficient in this transformation in terms of the regioselectivity, producing the desired products in excellent yield (99%). The efficiency of the Ru catalyst reached 580 (TON) and 156 min?1 (TOF).
