154879-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154879-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,8,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154879-03:
(8*1)+(7*5)+(6*4)+(5*8)+(4*7)+(3*9)+(2*0)+(1*3)=165
165 % 10 = 5
So 154879-03-5 is a valid CAS Registry Number.

The first total synthesis of benzopyranobenzazepine alkaloid (±)- clavizepine (1) has been achieved by using the Bradsher cyclization of the keto ester 16 (leading to 18) and the Pummerer-type cyclization of the sulfoxide 25 (leading to 26) as the key ste
