The CAS Registry Mumber 943749-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,7,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 943749-33:
(8*9)+(7*4)+(6*3)+(5*7)+(4*4)+(3*9)+(2*3)+(1*3)=205
205 % 10 = 5
So 943749-33-5 is a valid CAS Registry Number.

A Ramberg-Baecklund route to the stilbenoid anti-cancer agents combretastatin A-4 and DMU-212

Robinson, James E.,Taylor, Richard J. K.

, p. 1617 - 1619 (2008/02/08)

A concise route to combretastatin A-4, a potent inhibitor of tubulin polymerisation, using a Ramberg-Baecklund reaction to form the key (Z)-stilbene unit has been developed; this Ramberg-Baecklund approach has also been extended to prepare the (E)-stilbene DMU-212, which also possesses interesting growth inhibitory properties.
