Check Digit Verification of cas no

The CAS Registry Mumber 76401-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76401-91:
(7*7)+(6*6)+(5*4)+(4*0)+(3*1)+(2*9)+(1*1)=127
127 % 10 = 7
So 76401-91-7 is a valid CAS Registry Number.

Dichlorotris(dimethylamino)phosphorane as Dehydration Reagent for the Preparation of Activated (-ONp, -OPcp, -NSu)Esters of N-Protected Multifunctional Amino Acids

Appel, Rolf,Glaesel, Ursula

, p. 3511 - 3516 (2007/10/02)

Dichlorotris(dimethylamino)phosphorane (5) is an excellent reagent for the preparation of the activated esters of N-protected amino acids 7-9.Besides 4-nitrophenyl-, pentachlorophenyl-, and N-hydroxysuccinimide esters of various N-protected amino acids, in the presence of HOBt benzyloxycarbonyl-threonine N-hydroxysuccinimide ester was obtained for the first time.
