65141-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65141-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 65141-69:
(7*6)+(6*5)+(5*1)+(4*4)+(3*1)+(2*6)+(1*9)=117
117 % 10 = 7
So 65141-69-7 is a valid CAS Registry Number.

Efficient solid-phase synthesis of quinazoline-2-thioxo-4-ones with SynPhase(TM) lanterns
Makino,Suzuki,Nakanishi,Tsuji
, p. 8333 - 8337 (2000)
We wish to report the efficient solid-phase synthesis of diverse quinazoline-2-thioxo-4-ones using SynPhase(TM) lanterns as solid supports. Although target compounds were obtained only with low purity using Wang resin, lanterns derivatized with long chain
