Check Digit Verification of cas no

The CAS Registry Mumber 442159-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,1,5 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 442159-44:
(8*4)+(7*4)+(6*2)+(5*1)+(4*5)+(3*9)+(2*4)+(1*4)=136
136 % 10 = 6
So 442159-44-6 is a valid CAS Registry Number.

Synthetic studies on a cyclic hexadepsipeptide GE3: Stereoselective construction of the acyl side chain segment

Makino, Kazuishi,Henmi, Yoshiaki,Hamada, Yasumasa

, p. 613 - 615 (2007/10/03)

Stereoselective synthesis of the acyl side chain segment 2 of GE3 (1), a potent inhibitor of cell progression of the cell cycle from the G1 to S phase, has been achieved by using Sharpless' asymmetric dihydroxylation and Evans' and Paterson's stereoselective aldol methodologies.
