494210-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 494210-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,2,1 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 494210-34:
(8*4)+(7*9)+(6*4)+(5*2)+(4*1)+(3*0)+(2*3)+(1*4)=143
143 % 10 = 3
So 494210-34-3 is a valid CAS Registry Number.

A strategy for the synthesis of sulfated peptides
Young, Travis,Kiessling, Laura L.
, p. 3449 - 3451 (2007/10/03)
Reversible blockage of the tyrosine phenol group leads to an efficient solid-phase strategy for the synthesis of sulfated peptides using an azidomethyl (Azm) protected tyrosine building block (1). The protected tyrosine derivative is compatible with stand
