1341217-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1341217-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,2,1 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1341217-07:
(9*1)+(8*3)+(7*4)+(6*1)+(5*2)+(4*1)+(3*7)+(2*0)+(1*7)=109
109 % 10 = 9
So 1341217-07-9 is a valid CAS Registry Number.

A new method was developed for the synthesis of 6,7-dihydro-5H-pyrimido[4, 5-e][1,4]diazepin-8(9H)-one derivatives. The key to construct the pyrimido[4,5-e][1,4]diazepine core is the intramolecular amidation of N-((4-amino-6-chloropyrimidin-5-yl)methyl)-s
