Check Digit Verification of cas no

The CAS Registry Mumber 253192-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,9 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 253192-56:
(8*2)+(7*5)+(6*3)+(5*1)+(4*9)+(3*2)+(2*5)+(1*6)=132
132 % 10 = 2
So 253192-56-2 is a valid CAS Registry Number.

Synthetic applications of asymmetric Horner-Wadsworth-Emmons condensations: Approaches to marine natural products

Tullis, Joshua S.,Helquist, Paul,Rein, Tobias

, p. 165 - 168 (1999)

Asymmetric HWE condensations of meso-dialdehyde 1 with chiral phosphonates containing 8-phenylmenthol very directly generate chiral moieties that are seen in a number of cytotoxic natural products. The HWE reactions proceed in good yields with synthetical
