The CAS Registry Mumber 1321606-21-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,6,0 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1321606-21:
(9*1)+(8*3)+(7*2)+(6*1)+(5*6)+(4*0)+(3*6)+(2*2)+(1*1)=106
106 % 10 = 6
So 1321606-21-6 is a valid CAS Registry Number.

Four iodine-mediated electrophilic cyclizations of rigid parallel triple bonds mapped from 1,8-dialkynylnaphthalenes

Chen, Xiaopeng,Lu, Ping,Wang, Yanguang

supporting information; experimental part, p. 8105 - 8114 (2011/09/13)

Four different types of fused arenes, including fluoranthene, indeno[2,1-a]phenalene, (8H)cyclopenta[a]acenaphthylene, and pyridine[a]acenaphthylene, were efficiently constructed through iodine-mediated electrophilic cyclizations of 1,8-dialkynyl naphthal
