123771-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123771-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,7 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123771-37:
(8*1)+(7*2)+(6*3)+(5*7)+(4*7)+(3*1)+(2*3)+(1*7)=119
119 % 10 = 9
So 123771-37-9 is a valid CAS Registry Number.

Sodium periodate oxidation of tetrahydro-β-carboline derivatives [1]
Gatta,Misiti
, p. 537 - 539 (2007/10/02)
The oxidation of some 3-(methoxy- and ethoxycarbonyl)tetrahydro-β-carboline derivatives with sodium periodate led to the formation of 1,4-benzodiazonine derivatives or fully aromatic β-carbolines depending on both nature and number of substituents at 1-po
