Check Digit Verification of cas no

The CAS Registry Mumber 1333259-57-6 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 1333259-57:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*5)+(3*9)+(2*5)+(1*7)=146

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

supporting information; experimental part, p. 5342 - 5345 (2011/12/02)

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
