1273550-87-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1273550-87-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,5 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1273550-87:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*5)+(3*0)+(2*8)+(1*7)=160
160 % 10 = 0
So 1273550-87-0 is a valid CAS Registry Number.

Radical cyclizations of acylsilanes in the synthesis of (+)-swainsonine and formal synthesis of (-)-epiquinamide
Chen, Ming-Jen,Tsai, Yeun-Min
, p. 1564 - 1574 (2011/04/15)
Radical cyclization of acylsilane is an useful synthetic methodology. To demonstrate the versatility of this method using the cyclization as a key step, polyhydroxylated indolizidine (+)-swainsonine was synthesized through two different bond connection ap
