902775-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 902775-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,7,7 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 902775-77:
(8*9)+(7*0)+(6*2)+(5*7)+(4*7)+(3*5)+(2*7)+(1*7)=183
183 % 10 = 3
So 902775-77-3 is a valid CAS Registry Number.

Stereoselective approach to pentenocins using RCM: synthesis of 6-epi-pentenocin B
Venkata Ramana,Venkateswara Rao
, p. 4441 - 4443 (2007/10/03)
The stereoselective synthesis of 6-epi-pentenocin B 3 is described using a stereoselective Grignard reaction and ring-closing metathesis (RCM) as the key steps.
