Check Digit Verification of cas no

The CAS Registry Mumber 117157-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,5 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117157-37:
(8*1)+(7*1)+(6*7)+(5*1)+(4*5)+(3*7)+(2*3)+(1*7)=116
116 % 10 = 6
So 117157-37-6 is a valid CAS Registry Number.

Iridium-catalyzed highly enantioselective ring opening reaction of oxabenzonorbornadienes with amines

Zhou, Yongyun,Lu, Zhiwu,Han, Baiqiu,Zeng, Chaoyuan,Zhang, Zhenhua,Fan, Baomin

, p. 1354 - 1359 (2015/11/25)

The complex of [Ir(COD)Cl]2 and (R)-xylyl-phanephos was used as an effective catalyst for the asymmetric ring opening reaction of oxabenzonorbornadienes with various amines. Under the optimized reaction conditions, high enantioselectivities with moderate to good yields could be obtained from a wild scope of oxabenzonorbornadienes and amines.
