Check Digit Verification of cas no

The CAS Registry Mumber 1337877-10-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,8,7 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1337877-10:
(9*1)+(8*3)+(7*3)+(6*7)+(5*8)+(4*7)+(3*7)+(2*1)+(1*0)=187
187 % 10 = 7
So 1337877-10-7 is a valid CAS Registry Number.

Synthesis of spiroketals under neutral conditions via a type III ring-rearrangement metathesis strategy

Mandel, Jeremie,Dubois, Nathalie,Neuburger, Markus,Blanchard, Nicolas

, p. 10284 - 10286 (2011/11/04)

A conceptually novel approach to spiro- and dispiroketals of various ring-sizes under neutral conditions has been designed which complements the classical thermodynamically driven tactic. Key steps involved the formation of α-alkoxyfurans, their [4+2] or [4+3] cycloaddition reactions and the ring-rearrangement metathesis of the resulting oxabicycles.
