Check Digit Verification of cas no

The CAS Registry Mumber 56717-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,7,1 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56717-64:
(7*5)+(6*6)+(5*7)+(4*1)+(3*7)+(2*6)+(1*4)=147
147 % 10 = 7
So 56717-64-7 is a valid CAS Registry Number.

The organocatalytic synthesis of perfluorophenylsulfides: Via the thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates

Cai, Zhihua,Du, Guangfen,He, Lin,Lin, Muze,Luo, Jinyun,Wu, Leifang

supporting information, p. 9237 - 9241 (2021/11/13)

The organic superbase t-Bu-P4-catalyzed direct thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates was developed. Yields of perfluorophenylsulfides of up to 97% under catalysis of 5 mol% t-Bu-P4 were achieved. This method was shown to provide an efficient way to construct the perfluorophenyl-sulfur bond under mild metal-free reaction conditions. This journal is

EVIDENCE FOR INTRAMOLECULAR CYCLOADDITION PROCESS IN THE PHOTO-CLAISEN REARRANGEMENT

Sket, Boris,Zupancic, Natasa,Zupan, Marko

, p. 753 - 754 (2007/10/02)

Photoreaction of pentafluorophenyl-prop-2-enyl ether in cyclohexane at λ=253.7 nm resulted in intramolecular cycloaddition, forming 2,3,4,5,6-pentafluoro-1,8-epoximethano bicycloocta-2,4-diene, while a similar reaction of the thio analogue led to C - S bond cleavage.
