Check Digit Verification of cas no

The CAS Registry Mumber 404890-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,8,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 404890-45:
(8*4)+(7*0)+(6*4)+(5*8)+(4*9)+(3*0)+(2*4)+(1*5)=145
145 % 10 = 5
So 404890-45-5 is a valid CAS Registry Number.

Synthesis of the C1-C21 (C1'-C21') fragment of the dimeric polyketide natural product SCH 351448.

Bhattacharjee, Ashoke,Soltani, Omid,De Brabander, Jef K

, p. 481 - 484 (2007/10/03)

[structure: see text] A convergent, stereoselective assembly of the C1-C21 (C1'-C21') fragment of SCH 351448, a 28-membered bis-lactone natural product, has been developed. A highly efficient approach to this fragment assembles 75% of the carbon skeleton
