Check Digit Verification of cas no
The CAS Registry Mumber 116515-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,1 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116515-58:
(8*1)+(7*1)+(6*6)+(5*5)+(4*1)+(3*5)+(2*5)+(1*8)=113
113 % 10 = 3
So 116515-58-3 is a valid CAS Registry Number.

An Efficient Synthesis of Naphthalenic Lignan Lactones
Gokhale, S. M.,Joshi, R. R.,Narasimhan, N. S.
, p. 1030 - 1034 (2007/10/02)
Phthalides (1a-c) have been converted into the corresponding naphthalenic diesters (3a-c) and anhydrides (11, 15) through silyloxyisobenzofurans (2a-c), generated in situ, by reaction with respective dienophiles.The naphthalenic lignan lactones (4a-c), in
