Check Digit Verification of cas no

The CAS Registry Mumber 350620-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,6,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 350620-60:
(8*3)+(7*5)+(6*0)+(5*6)+(4*2)+(3*0)+(2*6)+(1*0)=109
109 % 10 = 9
So 350620-60-9 is a valid CAS Registry Number.

Double 1,4-addition of malonate to 1,2-diaza-1,3-butadienes: A useful route to previously unknown symmetric and unsymmetric 1,6-dioxo-2,7-diazaspiro [4.4] nona-3,8-dienes

Attanasi,De Crescentini,Filippone,Mantellini

, p. 534 - 537 (2007/10/03)

In the presence of sodium methoxide in tetrahydrofuran, 1,2-diaza-1,3-butadienes react with dimethyl malonate in a 2:1 molar ratio to give symmetric or unsymmetric bishydrazones that in turn produce new 1,6-dioxo-2,7-diazaspiro [4.4] nona-3,8-dienes, as a consequence of a double ring closure, on treatment with sodium methoxide in methanol.
