Check Digit Verification of cas no

The CAS Registry Mumber 1220284-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,2,8 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1220284-25:
(9*1)+(8*2)+(7*2)+(6*0)+(5*2)+(4*8)+(3*4)+(2*2)+(1*5)=102
102 % 10 = 2
So 1220284-25-2 is a valid CAS Registry Number.

Asymmetric SN 1 α-Alkylation of cyclic ketones catalyzed by functionalized chiral ionic liquid (FCIL) organocatalysts

Zhang, Long,Cui, Lingyun,Li, Xin,Li, Jiuyuan,Luo, Sanzhong,Cheng, Jin-Pei

supporting information; scheme or table, p. 2045 - 2049 (2010/06/15)

Ionic liquid works better: The first intermolecular asymmetric α-alkylation of cyclic ketones was realized by using functionalized chiral ionic liquids as catalysts. The reaction proceeded with good to excellent yields and high ee. Highly stereoselective desymmetrization of 4-substituted cyclohexanones with >99:1 d.r. and up to 87 % ee were achieved by using this protocol. (Chemical Equation Representation).
