Check Digit Verification of cas no

The CAS Registry Mumber 77249-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,4 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77249-39:
(7*7)+(6*7)+(5*2)+(4*4)+(3*9)+(2*3)+(1*9)=159
159 % 10 = 9
So 77249-39-9 is a valid CAS Registry Number.

The Seyferth reagent PhHgCBr3 generates singlet :CBr2 that adds nonstereospecifically to styrene and fumaronitrile via a carbene complex.

Stereomutation in the Seyferth Reaction

Lambert, Joseph B.,Larson, Eric G.,Bosch, Richard J.,Vrucht, Mollie L. E. Te

, p. 5443 - 5447 (2007/10/02)

The cyclopropanation reaction between dibromomethylene (:CBr2) from the Seyferth reagent (PhHgCBr3) and electron-deficient alkenes is nonstereospecific.Thus fumaronitrile, styrene-cis-β-d, and trans-1,2-dichloroethene give mixtures of the respective cis a
