Check Digit Verification of cas no

The CAS Registry Mumber 121416-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,1 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121416-52:
(8*1)+(7*2)+(6*1)+(5*4)+(4*1)+(3*6)+(2*5)+(1*2)=82
82 % 10 = 2
So 121416-52-2 is a valid CAS Registry Number.

APPLICATION DE LA REACTION DE PUMMERER A DES SULFOXYDE-ESTERS CHIRAUX DONNANT ACCES A DES Β-CETOESTERS CHIRAUX: LES (+)-(1S,2S,4R) ET (-)-(1R,2R,4S) OXO-3 BICYCLOHEPTENE-5 EXO-CARBOXYLATES-2 DE METHYLE

Guessous, Ahmed Radouane,Maignan, Christian

, p. 727 - 730 (2007/10/02)

Pummerer reaction when applied to adducts obtained through Diels-Alder reaction between methyl Z or E(R)3-p-tolyl-sulfinylpropenoate and cyclopentadiene yielded mostly (+) and (-)methyl-3-p-tolylthio bicyclo hepta-2,5-diene-2-carboxylates.Smooth acidic hydrolys of both enantiomeric vinyl sulfides enabled the first synthesis of chiral β-ketoesters: (+)-(1S,2S,4R) and (-)-(1R,2R,4S)methyl-3-oxo bicyclo hept-5-ene-2-carboxylates.
