Check Digit Verification of cas no

The CAS Registry Mumber 1621074-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,0,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621074-40:
(9*1)+(8*6)+(7*2)+(6*1)+(5*0)+(4*7)+(3*4)+(2*4)+(1*0)=125
125 % 10 = 5
So 1621074-40-5 is a valid CAS Registry Number.

Aerobic Dimerization of Enediyne Compounds: Construction of Naphthalene Frameworks

Wang, Dongxu,Ling, Fei,Liu, Xiang,Li, Zexiang,Ma, Cheng

supporting information, p. 124 - 128 (2016/01/25)

The first bimolecular oxygenative annulation of enediyne compounds leading to naphthalene frameworks has been developed by using Pd(OAc)2 as the catalyst in the presence of NaI under O2 (1 atm). This reaction provided efficient access to a class of symmetric core-annulated naphthalenes by the homoannulation of enediyne-imides. Intriguingly, the crossover annulation of enediyne-imides and other functionalized enediynes could also be achieved by the same catalytic system, resulting in the formation of several unsymmetrical naphthalene derivatives. Preliminary mechanistic investigation using 18O isotopic labelling and radical scavengers indicated that radical oxygen incorporation cascades might be involved in this conversion.
