Check Digit Verification of cas no

The CAS Registry Mumber 1258864-02-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,8,6 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1258864-02:
(9*1)+(8*2)+(7*5)+(6*8)+(5*8)+(4*6)+(3*4)+(2*0)+(1*2)=186
186 % 10 = 6
So 1258864-02-6 is a valid CAS Registry Number.

Sato, Yosuke,Fukuda, Hayato,Tomizawa, Masaki,Masaki, Tomohito,Shibuya, Masatoshi,Kanoh, Naoki,Iwabuchi, Yoshiharu

, p. 2239 - 2246 (2011/04/15)

The enantio-and diastereocontrolled total synthesis of (-)-salinosporamide A, a potent 20S proteasome inhibitor, was accomplished through organocatalytic aldolization, diastereoselective Claisen condensation, a Rh-catalyzed Reformatsky reaction, and an AZADO-catalyzed oxidative β-lactonization reaction as the key reactions.
