646054-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 646054-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,6,0,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 646054-34:
(8*6)+(7*4)+(6*6)+(5*0)+(4*5)+(3*4)+(2*3)+(1*4)=154
154 % 10 = 4
So 646054-34-4 is a valid CAS Registry Number.

The First Direct Chlorination of Iodoarenes - A Side-chain Directed Process
Mirk, Daniela,Kataeva, Olga,Froehlich, Roland,Waldvogel, Siegfried R.
, p. 2410 - 2414 (2007/10/03)
The chlorination of electron rich iodoarenes with MoCl5 proceeds with methoxycarbonylmethyl as the directing group. The transformation is selective and without loss of the valuable iodo substituent.
