Check Digit Verification of cas no

The CAS Registry Mumber 155623-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,2 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155623-52:
(8*1)+(7*5)+(6*5)+(5*6)+(4*2)+(3*3)+(2*5)+(1*2)=132
132 % 10 = 2
So 155623-52-2 is a valid CAS Registry Number.

Towards the Synthesis of the C37-C42 Fragment of Rapamycin: Intramolecular Reactions of Allyl Silanes with Oxonium Ions Generated from α-Alkoxy Sulfones.

Ley, Steven V.,Kouklovsky, Cyrille

, p. 835 - 848 (1994)

A new method for the formation of methylene cyclohexane derivatives has been developed, using intramolecular trapping by allyl silanes of oxonium ions generated from α-alkoxysulfones.These acyclic precursors were prepared by quenching the anion of methoxy
