155666-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155666-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,6 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155666-34:
(8*1)+(7*5)+(6*5)+(5*6)+(4*6)+(3*6)+(2*3)+(1*4)=155
155 % 10 = 5
So 155666-34-5 is a valid CAS Registry Number.

, p. 387 - 400 (2007/10/02)
Hybrid tilivallines (4), derived from tilivalline (1a) and anthramycin (2) or tomaymycin (3), and their 11-cyano analogs (15) have been efficiently synthesized from the acetal amides (7a, b) : the key step is an intramolecular Mannich type cyclization acc
