Check Digit Verification of cas no

The CAS Registry Mumber 1447498-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,4,9 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1447498-11:
(9*1)+(8*4)+(7*4)+(6*7)+(5*4)+(4*9)+(3*8)+(2*1)+(1*1)=194
194 % 10 = 4
So 1447498-11-4 is a valid CAS Registry Number.

Syntheses of hydrazino peptides and conjugates

Panda, Siva S.,El-Nachef, Claudia,Bajaj, Kiran,Katritzky, Alan R.

, p. 4156 - 4162 (2013/07/19)

(α-Benzyloxycarbonyl-aminoacyl)benzotriazolides (Cbz = benzyloxycarbonyl) underwent a coupling reaction with α-hydrazino acids under microwave irradiation to form hybrid hydrazino dipeptides (42-71 %). Chiral acylations of β-N-Cbz-α-hydrazino acylbenzotriazolides were successfully carried out with N-, S-, O-, and C-nucleophiles in yields of 49-88 %. Benzyloxycarbonyl-protected hybrid hydrazino dipeptides and benzyloxycarbonyl-protected hydrazino aminoacyl conjugates with N-, S-, O-, and C-nucleophiles were prepared by using benzotriazole methodology.
