49837-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49837-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,3 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 49837-70:
(7*4)+(6*9)+(5*8)+(4*3)+(3*7)+(2*7)+(1*0)=169
169 % 10 = 9
So 49837-70-9 is a valid CAS Registry Number.

Synthesis of New 1Н-Pyrrolo[3,4-с]pyridine-1,3(2Н)-diones
Klyuchko,Chumachenko,Shablykin,Brovarets
, p. 348 - 356 (2021/04/26)
Abstract: A method for the synthesis of a series of new substituted 1H-pyrrolo[3,4-c]pyridine-1,3(2H)-diones was proposed based on the Diels–Alder type reaction of 4-methoxy-1,3-oxazoles with maleimide derivatives.
