Check Digit Verification of cas no
The CAS Registry Mumber 132339-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,3 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132339-92:
(8*1)+(7*3)+(6*2)+(5*3)+(4*3)+(3*9)+(2*9)+(1*2)=115
115 % 10 = 5
So 132339-92-5 is a valid CAS Registry Number.

STRUCTURE OF 6- OR 8-ISOPRENOID SUBTITUTED FLAVANONE: CHEMICAL SHIFT OF THE HYDROGEN-BONDED HYDROXYL GROUP
Fukai, Toshio,Nomura, Taro
, p. 1861 - 1872 (2007/10/02)
The proton signal of the hydrogen-bonded hydroxyl group of the 6-isoprenoid substituted flavanone was shifted more downfield than that of 6-nonsubstituted flavanone.By comparison of the chemical shifts of the hydrogen-bonded hydroxyl groups of 8-(3",3"-di
