Check Digit Verification of cas no

The CAS Registry Mumber 152297-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,2,9 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 152297-95:
(8*1)+(7*5)+(6*2)+(5*2)+(4*9)+(3*7)+(2*9)+(1*5)=145
145 % 10 = 5
So 152297-95-5 is a valid CAS Registry Number.

EFFICIENT MICHAEL ADDITION REACTIONS OF THE N-ARYLSULFONYL-3-PHENYLTHIOPIPERIDONES. SYNTHESIS OF 3-SUBSTITUTED DIHYDROPYRIDINONES

Nakagawa, Masako,Torisawa, Yasuhiro,Hosaka, Toshihiro,Tanabe, Kiyoshi,Tavet, Fabrice,et al.

, p. 1157 - 1170 (2007/10/02)

Efficient methods for the Michael addition reactions of N-arylsulfonyl-3-phenylthiopiperidones (1) with both the protected amidoacrylates (4, 9) and the simple acrylates (12) have been developed.These reactions offer an efficient route to the 3-alkyl-substituted dihydropyridinones (3, 11), the dienophiles employed in the natural product synthesis.
