Check Digit Verification of cas no
The CAS Registry Mumber 3956-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3956-91:
(6*3)+(5*9)+(4*5)+(3*6)+(2*9)+(1*1)=120
120 % 10 = 0
So 3956-91-0 is a valid CAS Registry Number.

7-Hydroxyphthalide: A new natural salicylaldehyde analog from Oulenzia sp. (Astigmata: Winterschmitiidae)
Shimizu, Nobuhiro,Kuwahara, Yasumasa
, p. 990 - 992 (2001)
A new salicyl lactone was detected from the unidentified Oulenzia sp. and its chemical structure was elucidated as 7-hydroxyphthalide (7-hydroxy-3H-isobenzofuran-1-one), based on its GC/MS and GC/FT-IR data and SiO2 column behavior. The compound was synthesized by NaBH4 reduction of 3-hydroxyphthalic anhydride. The GC/MS and GC/FT-IR spectra of the natural compound were consistent with those of the synthetic product. Although the compound is known as a medical material, this is the first example of its presence in nature.
