1259371-50-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1259371-50-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,7 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1259371-50:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*7)+(3*1)+(2*5)+(1*0)=170
170 % 10 = 0
So 1259371-50-0 is a valid CAS Registry Number.

An Efficient Synthesis of Tetracyclic Pyrano[2,3-d]pyrimidines
Lin, Zhi-Lan,Zhang, Jun-Min,Gao, Yuan
, p. 596 - 602 (2017)
A series of pyrano[2,3-d]pyrimidine derivatives have been synthesized by the reaction of 2-amino-3-cyano-4H-pyrans and acetic anhydride with acid catalyst. This method is very efficient because of short reaction times and easy work-up, and it provides an
