Check Digit Verification of cas no

The CAS Registry Mumber 1250395-72-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,3,9 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1250395-72:
(9*1)+(8*2)+(7*5)+(6*0)+(5*3)+(4*9)+(3*5)+(2*7)+(1*2)=142
142 % 10 = 2
So 1250395-72-2 is a valid CAS Registry Number.

Total synthesis of peloruside a through kinetic lactonization and relay ring-closing metathesis cyclization reactions

Hoye, Thomas R.,Jeon, Junha,Kopel, Lucas C.,Ryba, Troy D.,Tennakoon, Manomi A.,Wang, Yini

supporting information; experimental part, p. 6151 - 6155 (2010/11/18)

The other side: A convergent total synthesis of peloruside A (1) is described. The key strategic features are a diastereoselective lactonization to generate a C5-C9 valerolactone from the C2-symmetric ketone 3, and a relay ring-closing metathesis reaction to produce a dehydrovalerolactone 2. A new isomer of 1, the valerolactone isopeloruside A (iso-1), was identified. MOM=methoxymethyl.
