Check Digit Verification of cas no

The CAS Registry Mumber 73787-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,8 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73787-09:
(7*7)+(6*3)+(5*7)+(4*8)+(3*7)+(2*0)+(1*9)=164
164 % 10 = 4
So 73787-09-4 is a valid CAS Registry Number.

ASYMMETRIC TOTAL SYNTHESIS OF NATURAL (-)- AND UNNATURAL (+)-STEGANACIN DETERMINATION OF THE ABSOLUTE CONFIGURATION OF NATURAL ANTITUMOR STEGANACIN

Tomioka, Kiyoshi,Ishiguro, Tsuneo,Iitaka, Yoichi,Koga, Kenji

, p. 1303 - 1312 (2007/10/02)

A virtually complete asymmetric control in the synthesis of 2,3-disubstituted butan-4-olide (10) was demonstrated by employing the butenolide (12) as the chiral acceptor for the conjugate 1,4-addition.Highly efficient asymmetric total synthesis of natural (-)- and unnatural (+)-steganacin was accomplished.The absolute stereostructure of natural antitumor steganacin was determined to be 1.
