136506-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136506-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,0 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136506-63:
(8*1)+(7*3)+(6*6)+(5*5)+(4*0)+(3*6)+(2*6)+(1*3)=123
123 % 10 = 3
So 136506-63-3 is a valid CAS Registry Number.

A facile preparation of o-aminoheteroarenecarbothialdehydes
Becher,Jorgensen,Frydendahl,Falt-Hansen
, p. 609 - 612 (2007/10/02)
Reduction with hydrogen sulfide of heterocyclic o-azidoaldehydes yields the corresponding o-aminocarbothialdehydes as stable crystalline compounds. The reactions are exemplified in the pyrazole and indole series. The o-aminoheteroarencarbothialdehyde give
