Check Digit Verification of cas no

The CAS Registry Mumber 1018454-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,4,5 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1018454-69:
(9*1)+(8*0)+(7*1)+(6*8)+(5*4)+(4*5)+(3*4)+(2*6)+(1*9)=137
137 % 10 = 7
So 1018454-69-7 is a valid CAS Registry Number.

supporting information; experimental part, p. 1070 - 1076 (2009/06/20)

(Chemical Equation Presented) In pursuit of a better route: A new catalytic asymmetric synthesis of Tamiflu was developed. The key transformation was an asymmetric Diels-Alder-type reaction of 1 and 2 catalyzed by a barium/F 2-FujiCAPO complex in the presence of a CsF co-catalyst to construct the core of Tamiflu (see scheme; TMS=trimethylsilyl). The product was converted into Tamiflu in 11 steps on a gram scale.
