83848-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83848-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83848-77:
(7*8)+(6*3)+(5*8)+(4*4)+(3*8)+(2*7)+(1*7)=175
175 % 10 = 5
So 83848-77-5 is a valid CAS Registry Number.

, p. 805 - 808 (2007/10/02)
New synthetic routes to pyridopyrimidines starting with 5-amino-1,3,6-trimethyluracil (I) or 1,3,6-trimethyl-5-nitrouracil (X) are described.Thus, condensation of I with arylaldehydes gave 5-arylideneamino-1,3,6-trimethyluracils (IIa-h), which upon
