75235-68-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75235-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75235-68:
(7*7)+(6*5)+(5*2)+(4*3)+(3*5)+(2*6)+(1*8)=136
136 % 10 = 6
So 75235-68-6 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
