Check Digit Verification of cas no

The CAS Registry Mumber 1025510-63-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,5,1 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1025510-63:
(9*1)+(8*0)+(7*2)+(6*5)+(5*5)+(4*1)+(3*0)+(2*6)+(1*3)=97
97 % 10 = 7
So 1025510-63-7 is a valid CAS Registry Number.

Asymmetric total synthesis of (+)-curcutetraol and (+)-sydonol

Ito, Suguru,Zhang, Chenxia,Hosoda, Naoya,Asami, Masatoshi

experimental part, p. 9879 - 9884 (2009/04/03)

The asymmetric total syntheses of (+)-curcutetraol and (+)-sydonol, phenolic bisabolane-type sesquiterpenoids having chiral tertiary alcohol moiety in the o-position of a phenol, were achieved in high enantiomeric excesses (99% ee). The chiral tertiary benzylic alcohol moiety of these compounds was constructed by an asymmetric synthesis using an easily available chiral aminal, (-)-(2R,5S)-2-methoxycarbonyl-3-phenyl-1,3-diazabicyclo[3.3.0]octane. The absolute configurations of both (+)-curcutetraol and?(+)-sydonol have been assumed to be S-configuration based on the stereochemical course of the well established asymmetric synthesis used in the syntheses.
