Check Digit Verification of cas no

The CAS Registry Mumber 1198212-40-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,2,1 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1198212-40:
(9*1)+(8*1)+(7*9)+(6*8)+(5*2)+(4*1)+(3*2)+(2*4)+(1*0)=156
156 % 10 = 6
So 1198212-40-6 is a valid CAS Registry Number.

Construction of two vicinal quaternary carbons by asymmetric allylic alkylation: Total synthesis of hyperolactone C and (-)-biyouyanagin A

Du, Chao,Li, Liqi,Li, Ying,Xie, Zhixiang

supporting information; experimental part, p. 7853 - 7856 (2010/04/05)

Call on triple A: Palladium-catalyzed asymmetric allylic alkylation (Pd-AAA; see scheme) has enabled a concise and efficient synthesis of hyperolacto ne C and (-)-biyouyanagin A in only six (20% Overall yield) and seven (8% overall yield) steps, respectively. The enantiomers of these natural products were also prepared by exploiting the same methodology.
