269077-06-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 269077-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,0,7 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 269077-06:
(8*2)+(7*6)+(6*9)+(5*0)+(4*7)+(3*7)+(2*0)+(1*6)=167
167 % 10 = 7
So 269077-06-7 is a valid CAS Registry Number.

Studies directed toward the synthesis of cryptoheptine
Zhang, Pingsheng,Bierer, Donald E.
, p. 643 - 645 (2000)
Synthesis of 5,10-dihydro-10-methylindolo[3,2-b][1]benzazepin-12(11H)- one (2), an isomer of the reported structure for cryptoheptine (1), is presented. Attempts to convert 2 to 1 led to 10-methylindolo[3,2-b][1]- benzazepin-12-one (10), an oxidation prod
