405290-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 405290-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,2,9 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 405290-27:
(8*4)+(7*0)+(6*5)+(5*2)+(4*9)+(3*0)+(2*2)+(1*7)=119
119 % 10 = 9
So 405290-27-9 is a valid CAS Registry Number.

2,4-Dimethoxybenzyl: An amide protecting group for 2-acetamido glycosyl donors 1
Kelly, Nicholas M.,Jensen, Knud J.
, p. 537 - 548 (2007/10/03)
2,4-Dimethoxybenzyl (Dmob) was used as an amide protecting group for 2-acetamido glycosyl donors. The N-Dmob group was introduced by imine formation between 2,4-dimethoxybenzaldehyde and d-glucosamine, followed by per-O-acylation, reduction to form the am
