Check Digit Verification of cas no
The CAS Registry Mumber 195066-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,0,6 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195066-20:
(8*1)+(7*9)+(6*5)+(5*0)+(4*6)+(3*6)+(2*2)+(1*0)=147
147 % 10 = 7
So 195066-20-7 is a valid CAS Registry Number.

Novel synthesis of heterocyclic aryl amidines
Tommasi, Ruben A.,Macchia, William M.,Parker, David T.
, p. 5947 - 5950 (2007/10/03)
We have developed a novel amidine synthesis that allows the preparation of heterocyclic amidines that were previously unknown and difficult to prepare by published methods. The route involves the lithiation of heterocycles by the action of n-BuLi followed
