167390-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167390-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,3,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167390-17:
(8*1)+(7*6)+(6*7)+(5*3)+(4*9)+(3*0)+(2*1)+(1*7)=152
152 % 10 = 2
So 167390-17-2 is a valid CAS Registry Number.

Highly Effective Diastereodifferentiation of Meso-Dicarboxylic Anhydrides Using Sterically Congested Chiral N-Sulfonylaminoalcohols

Imado, Hideo,Ishizuka, Tadao,Kunieda, Takehisa

, p. 931 - 934 (2007/10/02)

The differentiation between enantiotopic carbonyl groups of cyclic meso-dicarboxylic anhydrides has been attained with excellent diastereofacial selectivity with an isomer ratio above 99:1 by treatment with the lithium salts of sterically hindered chiral
