Check Digit Verification of cas no

The CAS Registry Mumber 1020202-95-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,2,0 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1020202-95:
(9*1)+(8*0)+(7*2)+(6*0)+(5*2)+(4*0)+(3*2)+(2*9)+(1*5)=62
62 % 10 = 2
So 1020202-95-2 is a valid CAS Registry Number.

Allenl azide cycloaddtion chemistry. Photochemical initiation and cul mediation leads to improved regioselectivity

Feldman II, Ken S.,Hester, D. Keith,Lpez, Carlos Silva,Faza, Olalla Nieto

supporting information; experimental part, p. 1665 - 1668 (2009/04/10)

Irradiation of 2-(3-alkenyl)allenylphenyl azides in the presence of excess Cul furnished functionalized 2,3-cyclopentenylindoles in good yield with only trace amounts of competitive C-N-bonded regioisomeric products. These results represent a significant departure from the modest to-nonexistent regioselectivity that attended thermal cyclization of these allenyl azide substrates.
