656256-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 656256-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 656256-65:
(8*6)+(7*5)+(6*6)+(5*2)+(4*5)+(3*6)+(2*6)+(1*5)=184
184 % 10 = 4
So 656256-65-4 is a valid CAS Registry Number.

Efficient preparation of 1,4,8-trimethylcyclam and its conversion into a thioalkyl-pendant pentadentate chelate
Halfen, Jason A.,Young Jr., Victor G.
, p. 2894 - 2895 (2007/10/03)
A facile synthesis of 1,4,8-trimethylcyclam and a thioalkyl-pendant derivative are reported, and the X-ray crystal structure of a nickel(II) complex illustrates structural consequences of appending the thiolate donor onto the macrocycle.
