Check Digit Verification of cas no

The CAS Registry Mumber 1058705-71-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,8,7,0 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1058705-71:
(9*1)+(8*0)+(7*5)+(6*8)+(5*7)+(4*0)+(3*5)+(2*7)+(1*1)=157
157 % 10 = 7
So 1058705-71-7 is a valid CAS Registry Number.

Asymmetric synthesis of 3,4-annulated cyclopentenones from cycloalkenyl ketones and vinyl carbamates by diastereoselective carbonyl addition/conrotatory 4π ring closure

Siemer, Michael,Froehlich, Roland,Hoppe, Dieter

experimental part, p. 2264 - 2270 (2009/04/07)

1-Lithiated O-vinyl carbamates add with high induced diastereoselectivity onto enantiomerically pure cycloalk-1-enyl (1-dibenzylamino)alkyl ketones. Subsequent O-carbamoyl migration, followed by a torquoselective, antarafacial 4π ring closure, leads to ho
