213766-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213766-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,7,6 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213766-83:
(8*2)+(7*1)+(6*3)+(5*7)+(4*6)+(3*6)+(2*8)+(1*3)=137
137 % 10 = 7
So 213766-83-7 is a valid CAS Registry Number.

, p. 6369 - 6372 (2007/10/03)
The synthesis of the E ring of gambierol was achieved from D-ribose via the intramolecular reaction of allylstannane with an aldehyde as a key step. The undesired stereoisomer formed in this reaction was converted to the desired product by using DBU isome
