189953-34-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189953-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189953-34:
(8*1)+(7*8)+(6*9)+(5*9)+(4*5)+(3*3)+(2*3)+(1*4)=202
202 % 10 = 2
So 189953-34-2 is a valid CAS Registry Number.

, p. 4105 - 4115 (2007/10/03)

An improved synthesis of exo-heterocyclic dienes like TV-substituted 4,5-dimethylene 2-oxazolidinones 1, by a one-step method from diacetyl and isocyanates, was described. This highly convergent synthetic strategy has been successfully used for the prepar
