1333480-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1333480-37-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,4,8 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1333480-37:
(9*1)+(8*3)+(7*3)+(6*3)+(5*4)+(4*8)+(3*0)+(2*3)+(1*7)=137
137 % 10 = 7
So 1333480-37-7 is a valid CAS Registry Number.

Platinum-catalyzed cycloisomerization of 1,4-enynes via 1,2-alkenyl rearrangement
Sato, Takuma,Onuma, Toshiki,Nakamura, Itaru,Terada, Masahiro
, p. 4992 - 4995 (2011/11/14)
The cycloisomerization of 1,4-enyne 1 in the presence of platinum(II) catalyst afforded 1,2,3-trisubstituted 1H-indene 2 and 20 in good to excellent yields. The reaction proceeded through an unprecedented 1,2-alkenyl rearrangement that afforded a novel re
