Check Digit Verification of cas no

The CAS Registry Mumber 169176-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,1,7 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 169176-73:
(8*1)+(7*6)+(6*9)+(5*1)+(4*7)+(3*6)+(2*7)+(1*3)=172
172 % 10 = 2
So 169176-73-2 is a valid CAS Registry Number.

Synthesis of Weinreb amides using diboronic acid anhydride-catalyzed dehydrative amidation of carboxylic acids

Shimada, Naoyuki,Takahashi, Naoya,Ohse, Naoki,Koshizuka, Masayoshi,Makino, Kazuishi

supporting information, p. 13145 - 13148 (2020/11/09)

The first successful example of the direct synthesis of Weinreb amides using catalytic hydroxy-directed dehydrative amidation of carboxylic acids using the diboronic acid anhydride catalyst is described. The methodology is applicable to the concise syntheses of eight α-hydroxyketone natural products, namely, sattabacin, 4-hydroxy sattabacin, kurasoins A and B, soraphinols A and B, and circumcins B and C.
