646-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 646-34-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 646-34:
(5*6)+(4*4)+(3*6)+(2*3)+(1*4)=74
74 % 10 = 4
So 646-34-4 is a valid CAS Registry Number.
InChI:InChI=1/CH5N3.H2O4S/c2-1(3)4;1-5(2,3)4/h(H5,2,3,4);(H2,1,2,3,4)
