169944-42-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 169944-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,9,4 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 169944-42:
(8*1)+(7*6)+(6*9)+(5*9)+(4*4)+(3*4)+(2*4)+(1*2)=187
187 % 10 = 7
So 169944-42-7 is a valid CAS Registry Number.

(Figure Presented) The convergent synthesis of N-Boc-(2R,3R,8R,9R,4E,6E)-3- amino-9-methoxy-2,6,8-trimethyl-10-phenyldecadenoic acid (enantio-N-Boc-ADDA) is reported. Our flexible approach takes advantage of highly efficient non-aldol aldol and cross-metathesis methodologies.
