Check Digit Verification of cas no

The CAS Registry Mumber 1256362-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1256362-40:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*6)+(3*2)+(2*4)+(1*0)=149
149 % 10 = 9
So 1256362-40-9 is a valid CAS Registry Number.

Chiral cyclobutane synthesis by exploiting a heteroatom-directed conjugate addition

Tsao, Kuo-Wei,Isobe, Minoru

supporting information; experimental part, p. 5338 - 5341 (2011/01/05)

The syntheses of both enantiomers of cyclobutanes B and ent-B are achieved through heteroatom-directed conjugate addition (HADCA) of nucleophiles to the epoxyvinylsulfone-substituted carbohydrates A and ent-A, which provided carbanions that intramolecularly attacked the epoxide with concomitant formation of the cyclobutane ring.
