357958-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 357958-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,9,5 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 357958-77:
(8*3)+(7*5)+(6*7)+(5*9)+(4*5)+(3*8)+(2*7)+(1*7)=211
211 % 10 = 1
So 357958-77-1 is a valid CAS Registry Number.

Efficient introduction of protected guanidines in boc solid phase peptide synthesis.
Zhang,Kennan
, p. 2341 - 2344 (2001)
[reaction: see text] Reaction of primary amines with pyrazole 1 results in rapid and efficient guanidinylation, either in solution or on solid phase. The reaction affords sulfonamide-protected products required for BOC solid phase peptide synthesis (SPPS)
