Check Digit Verification of cas no

The CAS Registry Mumber 173240-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 173240-55:
(8*1)+(7*7)+(6*3)+(5*2)+(4*4)+(3*0)+(2*5)+(1*5)=116
116 % 10 = 6
So 173240-55-6 is a valid CAS Registry Number.

Total synthesis of bryostatin 16 using a Pd-catalyzed diyne coupling as macrocyclization method and synthesis of C20-epi-bryostatin 7 as a potent anticancer agent

Trost, Barry M.,Dong, Guangbin

supporting information; experimental part, p. 16403 - 16416 (2011/02/23)

Asymmetric total synthesis of bryostatin 16 was achieved in 26 steps in the longest linear sequence and in 39 total steps from aldehyde 10. A Pd-catalyzed alkyne-alkyne coupling was employed for the first time as a macrocyclization method in a natural pro
