Check Digit Verification of cas no
The CAS Registry Mumber 78317-88-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,1 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78317-88:
(7*7)+(6*8)+(5*3)+(4*1)+(3*7)+(2*8)+(1*8)=161
161 % 10 = 1
So 78317-88-1 is a valid CAS Registry Number.

The first asymmetric decarboxylative [4 + 3] annulation of propargylic carbamates with C,N-cyclic azomethine imines has been developed successfully by a copper-N-heterocyclic carbine system. This strategy led to a series of optically active isoquinoline-f
