226417-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 226417-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,4,1 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 226417-44:
(8*2)+(7*2)+(6*6)+(5*4)+(4*1)+(3*7)+(2*4)+(1*4)=123
123 % 10 = 3
So 226417-44-3 is a valid CAS Registry Number.

DMAP-promoted racemization-free deacylation of carboxthioimide adducts: Carboxthioimide as a versatile carboxy protecting group
Su, Dah-Wei,Wang, Ying-Chuan,Yan, Tu-Hsin
, p. 545 - 546 (2007/10/03)
The DMAP-promoted deacylation of carboxthioimide adducts can be directed to form either acid or various ester protecting groups with no detectable levels of epimerization.
