Check Digit Verification of cas no

The CAS Registry Mumber 200576-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 200576-22:
(8*2)+(7*0)+(6*0)+(5*5)+(4*7)+(3*6)+(2*2)+(1*2)=93
93 % 10 = 3
So 200576-22-3 is a valid CAS Registry Number.

, p. 3613 - 3619 (2007/10/03)

Deprotonation of 3,4-dihydro-6-(p-toluenesulfonylmethyl)-2H-pyran (2) with n-BuLi and alkylation of the lithiated allyl sulfone gives good to excellent yields of monoalkylated products 3. No γ-substitution is observed in the monoalkylated products. A seco
