696-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 696-67-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 696-67:
(5*6)+(4*9)+(3*6)+(2*6)+(1*7)=103
103 % 10 = 3
So 696-67-3 is a valid CAS Registry Number.

The alkenyl radical generated from (-)-8-phenylmenthyl 7-iodo-2,6-heptadienoate smoothly cyclized to afford (R)-(2-cyclopentenyl)acetate with 88% de in 90% yield. (R)-(2-Cyclohexenyl)acetate was also obtained with 84% de in 72% yield under the same conditions. The presence of Lewis acid is essential for high diastereoselectivity and chemical yield.
