Check Digit Verification of cas no

The CAS Registry Mumber 117535-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,3 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117535-81:
(8*1)+(7*1)+(6*7)+(5*5)+(4*3)+(3*5)+(2*8)+(1*1)=126
126 % 10 = 6
So 117535-81-6 is a valid CAS Registry Number.

Synthesis of 5,6-Dihydro-4H-thiopyran-4-ones

Becher, Jan,Brondum, Klaus,Hansen, Poul,Jacobsen, Jens Peter

, p. 795 - 798 (2007/10/02)

The anions of 1,4-diaryl-3-buten-2-ones 1 reacts with arylisothiacyanates, yielding intermediates 4 which can ring close to 5,6-dihydro-4H-thiopyran-4-ones 5.Under similar reaction conditions ethyl 3-oxo-4-pentenoates 7 gives the 6-spiropyrans 9.Methylation of 3 gives the S-methylated open form 6.
