Check Digit Verification of cas no
The CAS Registry Mumber 253779-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,7 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253779-11:
(8*2)+(7*5)+(6*3)+(5*7)+(4*7)+(3*9)+(2*1)+(1*1)=162
162 % 10 = 2
So 253779-11-2 is a valid CAS Registry Number.

Reaction of 5-amino-1,3-dimethylpyrrolo[3,2-d]pyrimidine-2,4-(1H,3H)-diones with β-diketones produces enaminoketones. Some of these are converted by Lewis acids into pyrrolopyridazines. 1999 KluwerAcademic/Plenum Publishers.
