Check Digit Verification of cas no

The CAS Registry Mumber 104165-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,6 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104165-17:
(8*1)+(7*0)+(6*4)+(5*1)+(4*6)+(3*5)+(2*1)+(1*7)=85
85 % 10 = 5
So 104165-17-5 is a valid CAS Registry Number.

A Stable Methyleneketene and the Stepwise Fragmentation of Meldrum's Acids

Lorencak, Primoz,Pommelet, J. C.,Chuche, Josselin,Wentrup, Curt

, p. 369 - 370 (1986)

Mild flash vacuum pyrolysis of the Meldrum's acid derivative (3) gives the first example of a methylenemalonic anhydride (4), which decarboxylates in solution to give the first isolable methyleneketene (5); the structures are supported by (13)C n.m.r. spectra and chemical reactions.
