1354012-74-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1354012-74-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,0,1 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1354012-74:
(9*1)+(8*3)+(7*5)+(6*4)+(5*0)+(4*1)+(3*2)+(2*7)+(1*4)=120
120 % 10 = 0
So 1354012-74-0 is a valid CAS Registry Number.

A versatile route to N, N′-tetraaryl-substituted 2,5- diaminothiophenes
Heichert, Christoph,Wrackmeyer, Marion,Hartmann, Horst
experimental part, p. 3375 - 3378 (2011/11/30)
By reaction of N,N-tetraaryl-substituted succinic di-amides with Lawessons reagent, a series of N,N-tetraaryl-substituted 2,5-diaminothiophenes was prepared. The N,N-tetrakis(4-bromophenyl)-2,5-diaminothiophene, thus available, was used as an educt for th
