Check Digit Verification of cas no

The CAS Registry Mumber 132111-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132111-67:
(8*1)+(7*3)+(6*2)+(5*1)+(4*1)+(3*1)+(2*6)+(1*7)=72
72 % 10 = 2
So 132111-67-2 is a valid CAS Registry Number.

Triethylborane Induced Perfluoroalkylation of Silyl Enol Ethers and Ketene Silyl Acetals with Perfluoroalkyl Iodides

Miura, Katsukiyo,Takeyama, Yoshihiro,Oshima, Koichiro,Utimoto, Kiitiro

, p. 1542 - 1553 (2007/10/02)

Reaction of perfluoroalkyl iodides with silyl enol ethers mediated by Et3B in the presence of base such as 2,6-dimethylpyridine provides mixtures of perfluoroalkylated trialkylsilyl enol ethers and α-perfluoroalkylated ketones.The yield and distribution of the products heavily depend on the nature of base employed.Treatment of a reaction mixture consisting of perfluoroalkylated silyl enol ether and α-perfluoroalkylated ketone with concd HCl in THF gives α-perfluoroalkylated ketone as a single product.Reaction of ketene silyl acetals with perfluoroalkyl iodides in the absence of base affords α-perfluoroalkylated esters in excellent yields.
