Check Digit Verification of cas no

The CAS Registry Mumber 109922-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109922-52:
(8*1)+(7*0)+(6*9)+(5*9)+(4*2)+(3*2)+(2*5)+(1*2)=133
133 % 10 = 3
So 109922-52-3 is a valid CAS Registry Number.

Total Synthesis of Optically Active Integerrimine, a Twelve-membered Dilactonic Pyrrolizidine Alkaloid of Retronecine Type

Niwa, Haruki,Miyachi, Yasuyoshi,Okamoto, Osamu,Uosaki, Youichi,Kuroda, Akio,et al.

, p. 393 - 412 (2007/10/02)

A total synthesis of the natural enantiomer of integerrimine (1), a twelve-membered dilactonic pyrrolizidine alkaloid of retronecine type has been achieved through the enantioselective synthesis and regioselective coupling of (+)-retronecine (4) and (+)-integerrinecic acid (methylthio)methyl ether (6).
