Check Digit Verification of cas no

The CAS Registry Mumber 481048-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,1,0,4 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 481048-26:
(8*4)+(7*8)+(6*1)+(5*0)+(4*4)+(3*8)+(2*2)+(1*6)=144
144 % 10 = 4
So 481048-26-4 is a valid CAS Registry Number.

supporting information; experimental part, p. 15636 - 15641 (2010/01/30)

With sequential use of catalytic asymmetric Cr-mediated coupling reactions, E7389 C14-C35 and halichondrin C14-C38 building blocks have been stereoselectively synthesized. The C19-C20 bond is first formed via the catalytic asymmetric Ni/Cr-mediated coupli
