1421315-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421315-17-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,1 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1421315-17:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*1)+(3*5)+(2*1)+(1*7)=104
104 % 10 = 4
So 1421315-17-4 is a valid CAS Registry Number.

Xing, Ping,Huang, Zuo-Gang,Jin, Yun,Jiang, Biao
, p. 699 - 702 (2013/02/25)
Co2(CO)8 was found to be effective for cycloisomerization reaction of arylene 1,7-enynes to form 2,3-dihydroindene derivatives, and a catalytic version assisted by different Lewis base ligands was also studied.
