Check Digit Verification of cas no

The CAS Registry Mumber 1067658-69-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,6,5 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1067658-69:
(9*1)+(8*0)+(7*6)+(6*7)+(5*6)+(4*5)+(3*8)+(2*6)+(1*9)=188
188 % 10 = 8
So 1067658-69-8 is a valid CAS Registry Number.

Total synthesis of ciliatamides A-C: Stereochemical revision and the natural product-guided synthesis of unnatural analogs

Lewis, Jana A.,Daniels, R. Nathan,Lindsley, Craig W.

supporting information; experimental part, p. 4545 - 4548 (2009/05/27)

(Chemical Equation Presented) The first total synthesis of Ciliatamides A-C was completed, leading to a revision of the reported stereochemistry from (S,S) to the (R,R) enantiomers. Due to the expedited route, a library of over 50 unnatural ciliatamide analogs was also prepared.
