Check Digit Verification of cas no

The CAS Registry Mumber 309723-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,2 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 309723-69:
(8*3)+(7*0)+(6*9)+(5*7)+(4*2)+(3*3)+(2*6)+(1*9)=151
151 % 10 = 1
So 309723-69-1 is a valid CAS Registry Number.

Highly selective Diels-Alder reactions of dienophiles with 1,3-cyclohexadiene mediated by Yb(OTf)3·2H2O and ultrahigh pressures

Kinsman, Aaron C.,Kerr, Michael A.

, p. 3517 - 3520 (2000)

(Equation Presented) Ultrahigh pressures and catalytic Yb(OTf)3·2H20 were found to mediate Diels-Alder reactions of various electron-deficient dienophiles with 1,3-cyclohexadiene to produce endo-bicyclo[2.2.2]oct-2-enes in moderate t
