Check Digit Verification of cas no

The CAS Registry Mumber 216155-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,1,5 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216155-50:
(8*2)+(7*1)+(6*6)+(5*1)+(4*5)+(3*5)+(2*5)+(1*0)=109
109 % 10 = 9
So 216155-50-9 is a valid CAS Registry Number.

Controlling the regioselectivity of lithiation using kinetic isotope effects: Deuterium as a protecting group for carbon

Clayden, Jonathan,Pink, Jennifer H.,Westlund, Neil,Wilson, Francis X.

, p. 8377 - 8380 (1998)

By substituting deuterium for hydrogen at positions of high kinetic acidity in amides and carbamates, the usual regiochemical course of their reactions with alkyllithiums (ortholithiation vs. lateral lithiation vs. nucleophilic addition) can be altered or overturned by the kinetic isotope effect. The deuterium substituent functions in these reactions as a protecting group for carbon.
