Check Digit Verification of cas no

The CAS Registry Mumber 57756-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,5 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57756-07:
(7*5)+(6*7)+(5*7)+(4*5)+(3*6)+(2*0)+(1*7)=157
157 % 10 = 7
So 57756-07-7 is a valid CAS Registry Number.

Nickel-catalyzed cross-coupling of umpolung carbonyls and alkyl halides

Zhu, Dianhu,Lv, Leiyang,Qiu, Zihang,Li, Chao-Jun

, (2019/05/22)

An effective nickel-catalyzed cross-coupling of Umpolung carbonyls and alkyl halides was developed. Complementary to classical alkylation techniques, this reaction utilizes Umpolung carbonyls as the environmentally benign alkyl nucleophiles, providing an efficient and selective catalytic alternative to the traditional use of highly reactive alkyl organometallic reagents.
