Check Digit Verification of cas no

The CAS Registry Mumber 1637370-47-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,7,3,7 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1637370-47:
(9*1)+(8*6)+(7*3)+(6*7)+(5*3)+(4*7)+(3*0)+(2*4)+(1*7)=178
178 % 10 = 8
So 1637370-47-8 is a valid CAS Registry Number.

Cooperative activation with chiral nucleophilic catalysts and n-haloimides: Enantioselective iodolactonization of 4-arylmethyl-4-pentenoic acids

Nakatsuji, Hidefumi,Sawamura, Yasuhiro,Sakakura, Akira,Ishihara, Kazuaki

supporting information, p. 6974 - 6977 (2014/07/08)

Chiral triaryl phosphates promote the enantioselective iodolactonization of 4-substituted 4-pentenoic acids to give the corresponding iodolactones in high yields with high enantioselectivity. N-Chlorophthalimide (NCP) is employed as a Lewis acidic activat
