130877-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130877-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,7 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130877-77:
(8*1)+(7*3)+(6*0)+(5*8)+(4*7)+(3*7)+(2*7)+(1*7)=139
139 % 10 = 9
So 130877-77-9 is a valid CAS Registry Number.

Asymmetric synthesis of orsellinic acid type macrolides: The example of lasiodiplodin
Solladie,Rubio,Carreno,Ruano
, p. 187 - 198 (2007/10/02)
The asymmetric synthesis of both enantiomers of methyl lasiodiplodin is described. The chiral centers were created in the very last steps of the synthesis by asymmetric induction of a chiral sulfoxide group.
