Check Digit Verification of cas no

The CAS Registry Mumber 111558-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111558-33:
(8*1)+(7*1)+(6*1)+(5*5)+(4*5)+(3*8)+(2*3)+(1*3)=99
99 % 10 = 9
So 111558-33-9 is a valid CAS Registry Number.

, p. 125 - 132 (2007/10/02)

Salicylideneacetone (2a) reacts with cyclohexanone (8a) and NaH in DMSO to give predominantly the B/C-trans-hexahydropropanoxanthenone 11a, which may be converted into the B/C-cis-derivative yield by treatment with aqueous HCl. 2-Methylcyclohexanone (8b)
