1636155-42-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1636155-42-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,6,1,5 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1636155-42:
(9*1)+(8*6)+(7*3)+(6*6)+(5*1)+(4*5)+(3*5)+(2*4)+(1*2)=164
164 % 10 = 4
So 1636155-42-4 is a valid CAS Registry Number.

Convenient one-pot multicomponent strategy for the synthesis of 6-pyrrolylpyrimidines
Dhanalakshmi, Pandi,Shanmugam, Sivakumar
, p. 29493 - 29501 (2014/08/05)
We have developed an easy method to construct diheteroaryls from α-aroylidineketene dithioacetals in a multicomponent manner. The reaction proceeded with high chemo/regioselectivity to yield 4-alkoxy-6-(4-aryl-1H- pyrrol-3-yl)pyrimidin-2-amines under mild
