1242027-78-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1242027-78-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,2 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1242027-78:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*2)+(3*7)+(2*7)+(1*8)=116
116 % 10 = 6
So 1242027-78-6 is a valid CAS Registry Number.

New cyclization of 4-oxahepta-1,6-diynes bearing sulfur and selenium functional groups
Yoshimatsu, Mitsuhiro,Watanabe, Hiroyasu,Koketsu, Eri
supporting information; experimental part, p. 4192 - 4194 (2010/11/19)
New cyclizations of 1-sulfanyl- and -selanyl-4-oxa-1,6-heptadiynes using sodium alkoxide or thiolates provided 4-alkoxymethyl-3-phenylsulfanyl- and 3,4-bis(sulfanylmethyl)furans in high yields.
