Check Digit Verification of cas no

The CAS Registry Mumber 1040749-02-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,7,4 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1040749-02:
(9*1)+(8*0)+(7*4)+(6*0)+(5*7)+(4*4)+(3*9)+(2*0)+(1*2)=117
117 % 10 = 7
So 1040749-02-7 is a valid CAS Registry Number.

Cinchona alkaloid catalyzed enantioselective fluorination of allyl silanes, silyl enol ethers, and oxindoles

Ishimaru, Takehisa,Shibata, Norio,Horikawa, Takao,Yasuda, Naomi,Nakamura, Shuichi,Toru, Takeshi,Shiro, Motoo

supporting information; experimental part, p. 4157 - 4161 (2009/03/11)

(Chemical Equation Presented) Catalytic variant: Allyl silanes and silyl enol ethers 1 are good substrates for the catalytic highly enantioselective fluorodesilylation using a combination of a biscinchona alkaloid, N-fluorobenzenesulfonimide (NFSI), and base (see scheme). Pharmaceutically attractive 3-aryl-3-fluorooxindoles such as 3 can also be synthesized with high enantioselectivity.
