Check Digit Verification of cas no

The CAS Registry Mumber 119253-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,5 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119253-83:
(8*1)+(7*1)+(6*9)+(5*2)+(4*5)+(3*3)+(2*8)+(1*3)=127
127 % 10 = 7
So 119253-83-7 is a valid CAS Registry Number.

CHELATION-CONTROLLED CYCLIZATION OF β-KETOESTER-SUBSTITUTED AND β-KETOAMIDE-SUBSTITUTED ALLYLSILANES.

Molander, Gary A.,Andrews, Steven W.

, p. 3115 - 3118 (2007/10/02)

The first examples of Lewis acid-catalyzed chelation-controlled cyclization reactions are reported.Titanium tetrachloride-initiated cyclization of β-ketoester and β-ketoamide-substituted allylsilanes proceeds in isolated yields of 65-88percent, providing
