69543-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69543-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69543-90:
(7*6)+(6*9)+(5*5)+(4*4)+(3*3)+(2*9)+(1*0)=164
164 % 10 = 4
So 69543-90-4 is a valid CAS Registry Number.

Proline-based phosphoramidite reagents for the reductive ligation of S-nitrosothiols
Park, Chung-Min,Biggs, Tyler D.,Xian, Ming
, p. 313 - 318 (2016)
S-Nitrosothiols (RSNOs) have many biological implications but are rarely used in organic synthesis. In this work we report the development of proline-based phosphoramidite substrates that can effectively convert RSNOs to proline-based sulfenamides through
