188185-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188185-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,8 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188185-73:
(8*1)+(7*8)+(6*8)+(5*1)+(4*8)+(3*5)+(2*7)+(1*3)=181
181 % 10 = 1
So 188185-73-1 is a valid CAS Registry Number.

Brenner, Michael,Mayer, Guido,Terpin, Andreas,Steglich, Wolfgang
, p. 70 - 74 (1997)
Arcyriacyanin A (1) has been synthesized by three different routes. In the first synthesis the bisbromomagnesium salt of 2,4'-biindole (5) was treated with dibromomaleimide (6) to yield arcyriacyanin A (1). The second approach used an intramolecular Hock
