Check Digit Verification of cas no

The CAS Registry Mumber 1256795-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,7,9 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256795-49:
(9*1)+(8*2)+(7*5)+(6*6)+(5*7)+(4*9)+(3*5)+(2*4)+(1*9)=199
199 % 10 = 9
So 1256795-49-9 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
