Check Digit Verification of cas no

The CAS Registry Mumber 476312-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,6,3,1 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 476312-66:
(8*4)+(7*7)+(6*6)+(5*3)+(4*1)+(3*2)+(2*6)+(1*6)=160
160 % 10 = 0
So 476312-66-0 is a valid CAS Registry Number.

β-lactams as building blocks in the synthesis of macrocyclic spermine and spermidine alkaloids

Wasserman, Harry H,Matsuyama, Haruo,Robinson, Ralph P

, p. 7177 - 7190 (2002)

Syntheses of the macrocyclic spermidine alkaloids (±)-celacinnine (1) and (±)-dihydroperiphylline (2) as well as the related spermine alkaloid (±)-verbascenine (3) were accomplished by means of sequential ring expansions of smaller lactam rings. Three ring expansion methods were employed: (1) transamidation of N-(aminoalkyl)lactams, (2) β-lactam-lactim ether condensation followed by reductive cleavage of the bicyclic 4-oxotetrahydropyrimidine product with NaBH3CN/AcOH and (3) bicyclic acyl hydrazine formation followed by N-N bond cleavage with Na/NH3. Each synthesis features ring expansion of a 4-phenylazetidin-2-one intermediate that undergoes transamidative ring expansion or lactim ether condensation.
