618905-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 618905-01-4 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 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 618905-01:
(8*6)+(7*1)+(6*8)+(5*9)+(4*0)+(3*5)+(2*0)+(1*1)=164
164 % 10 = 4
So 618905-01-4 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
