869780-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869780-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,7,8 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 869780-50:
(8*8)+(7*6)+(6*9)+(5*7)+(4*8)+(3*0)+(2*5)+(1*0)=237
237 % 10 = 7
So 869780-50-7 is a valid CAS Registry Number.

Synthesis of novel mannose-based crown ethers
Rathjens,Thiem
, p. 211 - 222 (2007/10/03)
A novel class of chiral crown ether analogues incorporating carbohydrate subunits can be easily prepared from methyl α-D-mannopyranoside. By a short reaction sequence involving either alkylations using a dibutylstannane intermediate or by phase transfer c
