79356-61-9 Usage
General Description
CL-BK, also known as cyclopropyl fentanyl, is a potent synthetic opioid analgesic that has been identified as a controlled substance in several countries. It is a powerful analogue of fentanyl, a widely used prescription analgesic. CL-BK has been associated with numerous cases of overdose and adverse effects, including respiratory depression, sedation, and potential for addiction and dependence. It is a Schedule I controlled substance in the United States, meaning it has a high potential for abuse and no accepted medical use. Due to its potency and potential for harm, CL-BK is a highly regulated and restricted substance, and its use should be closely monitored by healthcare professionals.
Check Digit Verification of cas no
The CAS Registry Mumber 79356-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,5 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79356-61:
(7*7)+(6*9)+(5*3)+(4*5)+(3*6)+(2*6)+(1*1)=169
169 % 10 = 9
So 79356-61-9 is a valid CAS Registry Number.

Intramolecular Acetalization of 5-Hydroxy Ketones and Enones. A Novel Transformation of Important Prostaglandin Intermediates under Acidic Conditions
Schwarz, Sigfrid,Weber, Gisela,Palme, Hans-Joachim,Wentzke, Manfred
, p. 751 - 756 (2007/10/02)
Intermediates in the synthesis of ω-tetranor 16-aryloxy prostaglandins, which are 5-hydroxy enones undergo quantitative intramolecular transformation into cyclic methyl acetals in acidic methanolic solution.The reaction proceeds via the corresponding 5-hydroxy-3-methoxy ketones, which partly exist as hemiacetals.The structure of the compounds investigated was elucidated by 1H NMR spectroscopy and by X-ray analysis of the acetal (11).
