1421315-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421315-20-9 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, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421315-20:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*1)+(3*5)+(2*2)+(1*0)=99
99 % 10 = 9
So 1421315-20-9 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.
