84657-74-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84657-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,5 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84657-74:
(7*8)+(6*4)+(5*6)+(4*5)+(3*7)+(2*7)+(1*4)=169
169 % 10 = 9
So 84657-74-9 is a valid CAS Registry Number.

Photodimers of Isobenzofuran: a Novel Application of Lanthanide Induced Shift Spectroscopy to Determine Stereochemistry

Warrener, Ronald N.,Pitt, Ian G.,Russell, Richard A.

, p. 1195 - 1197 (1982)

In acetone solution u.v. irradiation of isobenzofuran at -60 deg C forms an dimer shown by lanthanide induced shift spectroscopy to have the anti-stereochemistry; in ether solution an dimer is obtained together with a skeletally modified dimer, the structure of which is confirmed by synthesis.
