Check Digit Verification of cas no

The CAS Registry Mumber 1210327-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,3,2 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1210327-90:
(9*1)+(8*2)+(7*1)+(6*0)+(5*3)+(4*2)+(3*7)+(2*9)+(1*0)=94
94 % 10 = 4
So 1210327-90-4 is a valid CAS Registry Number.

Highly enantioselective direct allylic alkylation of butenolides with Morita-Baylis-Hillman carbonates catalyzed by chiral squaramide-phosphine

Kang, Tian-Chen,Zhao, Xuan,Sha, Feng,Wu, Xin-Yan

, p. 74170 - 74173 (2015)

An efficient asymmetric vinylogous allylic alkylation of β,γ-butenolides with Morita-Baylis-Hillman carbonates has been developed. With a chiral cyclohexane-based squaramide-phosphine catalyst 5e, optically active γ,γ-disubstituted butenolides containing
