188950-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188950-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188950-57:
(8*1)+(7*8)+(6*8)+(5*9)+(4*5)+(3*0)+(2*5)+(1*7)=194
194 % 10 = 4
So 188950-57-4 is a valid CAS Registry Number.

, p. 251 - 258 (2007/10/03)
The synthesis of 1-(1,2-O-diundecyl-sn-glycerylphosphoryl) 4,5-D-myo-inosityl bisphosphate and its tritiated analog are described. The convergent synthesis employed optically-pure inositol and glycerol derivatives. In the final step, hydrogenation of an a
