Check Digit Verification of cas no
The CAS Registry Mumber 135085-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135085-91:
(8*1)+(7*3)+(6*5)+(5*0)+(4*8)+(3*5)+(2*9)+(1*1)=125
125 % 10 = 5
So 135085-91-5 is a valid CAS Registry Number.

Substituent Interaction with Ring Sulfur in some Heterocyclic Compounds
McKinnon, David M.,Abouzeid, A. A.
, p. 749 - 752 (2007/10/02)
The infrared carbonyl absorptions of 7-acetyl-1,2-benzisothiazoles are similar to 7-acetylbenzothiophenes, but are lower by approximately 15 cm-1 than the corresponding benzofurans.The reasons for this are discussed.
