1333259-59-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1333259-59-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,5 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1333259-59:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*5)+(3*9)+(2*5)+(1*9)=148
148 % 10 = 8
So 1333259-59-8 is a valid CAS Registry Number.

Efficient and direct nucleophilic difluoromethylation of carbonyl compounds and imines with Me3SiCF2H at ambient or low temperature
Zhao, Yanchuan,Huang, Weizhou,Zheng, Ji,Hu, Jinbo
, p. 5342 - 5345 (2011)
Since 1995, Me3SiCF2H has been widely believed to be an inefficient difluoromethylating agent, which requires harsh reaction conditions to cleave its rather inert Si-CF2H bond. However, it has now been found that, by using
