Check Digit Verification of cas no

The CAS Registry Mumber 138621-74-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138621-74:
(8*1)+(7*3)+(6*8)+(5*6)+(4*2)+(3*1)+(2*7)+(1*4)=136
136 % 10 = 6
So 138621-74-6 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive Allylation of Tertiary Alkyl Halides with Allylic Carbonates

Chen, Haifeng,Jia, Xiao,Yu, Yingying,Qian, Qun,Gong, Hegui

supporting information, p. 13103 - 13106 (2017/09/19)

The construction of all C(sp3) quaternary centers has been successfully achieved under Ni-catalyzed cross-electrophile coupling of allylic carbonates with unactivated tertiary alkyl halides. For allylic carbonates bearing C1 or C3 substituents, the reaction affords excellent regioselectivity through the addition of alkyl groups to the unsubstituted allylic carbon terminus. The allylic alkylation method also exhibits excellent functional-group compatibility, and delivers the products with high E selectivity.
