Check Digit Verification of cas no

The CAS Registry Mumber 1177258-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,7,2,5 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1177258-89:
(9*1)+(8*1)+(7*7)+(6*7)+(5*2)+(4*5)+(3*8)+(2*8)+(1*9)=187
187 % 10 = 7
So 1177258-89-7 is a valid CAS Registry Number.

Stereoselective synthesis of benzannulated spiroketals: Influence of the aromatic ring on reactivity and conformation

Liu, Guodong,Wurst, Jacqueline M.,Tan, Derek S.

, p. 3670 - 3673 (2011/03/18)

Image Presented A systematic stereocontrolled synthesis of benzannulated spiroketals has been developed, using kinetic spirocyclization reactions of glycal epoxides, leading to a new AcOH-induced cyclization and valuable insights into the reactivity and c
