Check Digit Verification of cas no

The CAS Registry Mumber 438625-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,6,2 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 438625-82:
(8*4)+(7*3)+(6*8)+(5*6)+(4*2)+(3*5)+(2*8)+(1*2)=172
172 % 10 = 2
So 438625-82-2 is a valid CAS Registry Number.

Asymmetric total synthesis of spongistatins 1 and 2

Crimmins, Michael T.,Katz, Jason D.,Washburn, David G.,Allwein, Shawn P.,McAtee, Laura F.

, p. 5661 - 5663 (2007/10/03)

The total synthesis of spongistatin 1 (1) and spongistatin 2 (2) has been achieved through an advanced-stage intermediate. The synthesis is highlighted by a highly convergent assembly of the four key fragments (the C1-C15 AB fragment 2, the C16-C28 CD fra
