618904-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 618904-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,9,0 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 618904-95:
(8*6)+(7*1)+(6*8)+(5*9)+(4*0)+(3*4)+(2*9)+(1*5)=183
183 % 10 = 3
So 618904-95-3 is a valid CAS Registry Number.

Novel Synthetic Approach to 6,7-Dihydro-5H-imidazo[1,5-a]-pyrazin-8-ones
Gopalsamy, Ariamala,Shi, Mengxiao
, p. 3907 - 3909 (2007/10/03)
(Matrix presented) A novel route to highly substituted chiral 6,7-dihydro-5H-imidazo[1,5-a]pyrazine-8-ones starting from Meldrum's acid is disclosed. The key features of the methodology are the incorporation of amino esters as a chiral pool and facile mil
