Check Digit Verification of cas no
The CAS Registry Mumber 556038-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,6,0,3 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 556038-76:
(8*5)+(7*5)+(6*6)+(5*0)+(4*3)+(3*8)+(2*7)+(1*6)=167
167 % 10 = 7
So 556038-76-7 is a valid CAS Registry Number.

, p. 6630 - 6631 (2007/10/03)
The total synthesis of (+)-duocarmycin A and SA through a common indoline intermediate is described. The key reactions include selective lithiation of a 2,6-dibromoiodobenzene derivative and diastereoselective addition to a chiral nitroalkene, copper-mediated aryl amination, and addition of aryllithium to azlactones.
