959977-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 959977-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,9,7 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 959977-81:
(8*9)+(7*5)+(6*9)+(5*9)+(4*7)+(3*7)+(2*8)+(1*1)=272
272 % 10 = 2
So 959977-81-2 is a valid CAS Registry Number.

Syntheses of 4,5-disubstituted oxazoles via regioselective C-4 bromination
Li, Bryan,Buzon, Richard A.,Zhang, Zhijun
, p. 951 - 955 (2012/12/30)
A scaleable and highly regioselective C-4 bromination of 5-substituted oxazoles is described. The use of DMF as solvent played a critical role in significantly improving the C-4/C-2 bromination ratio. The resulting 4-bromooxazoles were shown to be good Su
