188839-30-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188839-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,3 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188839-30:
(8*1)+(7*8)+(6*8)+(5*8)+(4*3)+(3*9)+(2*3)+(1*0)=197
197 % 10 = 7
So 188839-30-7 is a valid CAS Registry Number.

N-heterocyclic carbene-catalyzed benzoin strategy for divergent synthesis of cyclitol derivatives from alditols

Kang, Bubwoong,Sutou, Toshiaki,Wang, Yinli,Kuwano, Satoru,Yamaoka, Yousuke,Takasu, Kiyosei,Yamada, Ken-Ichi

, p. 131 - 147 (2015/01/30)

A divergent synthesis of cyclitol derivatives has been developed utilizing an N-heterocyclic carbene-catalyzed benzoin-type cyclization of C2-symmetrical dialdoses. The resulting inososes are versatile intermediates, which are readily converted
