125426-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125426-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,2 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125426-05:
(8*1)+(7*2)+(6*5)+(5*4)+(4*2)+(3*6)+(2*0)+(1*5)=103
103 % 10 = 3
So 125426-05-3 is a valid CAS Registry Number.

1,5-DIHYDRO-3H-2,4-BENZODIOXEPINE AS A NOVEL CARBONYL PROTECTING GROUP
Machinaga, Nobuo,Kibayashi, Chihiro
, p. 4165 - 4168 (1989)
A novel and facile protective group for carbonyl compounds as 1,5-dihydro-3H-2,4-benzodioxepine, which can be cleaved smoothly in a nonacidic manner by catalytic hydrogenolysis, has been demonstrated.
