Check Digit Verification of cas no

The CAS Registry Mumber 91350-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,5 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91350-79:
(7*9)+(6*1)+(5*3)+(4*5)+(3*0)+(2*7)+(1*9)=127
127 % 10 = 7
So 91350-79-7 is a valid CAS Registry Number.

Room Temperature, Reductive Alkylation of Activated Methylene Compounds: Carbon-Carbon Bond Formation Driven by the Rhodium-Catalyzed Water-Gas Shift Reaction

Denmark, Scott E.,Ibrahim, Malek Y. S.,Ambrosi, Andrea

, p. 613 - 630 (2017)

The rhodium-catalyzed water-gas shift reaction has been demonstrated to drive the reductive alkylation of several classes of activated methylene compounds at room temperature. Under catalysis by rhodium trichloride (2-3 mol %), carbon monoxide (10 bar), water (2-50 equiv), and triethylamine (2.5-7 equiv), the scope has been successfully expanded to cover a wide range of alkylating agents, including aliphatic and aromatic aldehydes, as well as cyclic ketones, in moderate to high yields. This method is comparable to, and for certain aspects, surpasses the established reductive alkylation protocols.
