Check Digit Verification of cas no
The CAS Registry Mumber 17647-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,4 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17647-57:
(7*1)+(6*7)+(5*6)+(4*4)+(3*7)+(2*5)+(1*7)=133
133 % 10 = 3
So 17647-57-3 is a valid CAS Registry Number.

Formamide Catalysis Facilitates the Transformation of Aldehydes into Geminal Dichlorides
Huy, Peter Helmut
supporting information, p. 2474 - 2483 (2019/06/08)
Herein, a novel method for the transformation of aldehydes into geminal dichlorides based on phthaloyl chloride as reagent and N -formylpyrrolidine as Lewis base catalyst is disclosed. Given the mild reaction conditions, the current protocol is distinguished by high levels of functional group compatibility and scalability and is operationally simple. The in situ formation of a Vilsmeier Haack reagent type intermediate is likely to be essential for this organocatalytic nucleophilic substitution reaction.
