Check Digit Verification of cas no

The CAS Registry Mumber 140860-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140860-61:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*0)+(2*6)+(1*1)=113
113 % 10 = 3
So 140860-61-3 is a valid CAS Registry Number.

Stereospecific Synthesis of the 2,3-trans-3,4-cis Trisubstituted Tetrahydrofuran Lignan(+/-)-Dihydrosesamin

Stevens, David R.,Whiting, Donald A.

, p. 633 - 637 (2007/10/02)

It is shown that the stereochemistry of additions to the 3-arylidene lactones 3 and 9 is controlled by the 5- rather than the 4-substituent; synthesis of the 2,3-trans-3,4-cis lignan dihydrosesamin 11b (R = H) thus requires use of the 4,5-cis- lactone 8,
