163351-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163351-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,3,5 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163351-90:
(8*1)+(7*6)+(6*3)+(5*3)+(4*5)+(3*1)+(2*9)+(1*0)=124
124 % 10 = 4
So 163351-90-4 is a valid CAS Registry Number.

, p. 2409 - 2420 (1995)
An efficient, general method for the synthesis of 1,2-hydroxy esters by regioselective nucleophilic opening of 1,2-cyclic carbonate systems has been developed. A reliable and practical route giving access to the taxoid carbonate 2 from the readily availab
