Check Digit Verification of cas no
The CAS Registry Mumber 6492-68-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,9 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6492-68:
(6*6)+(5*4)+(4*9)+(3*2)+(2*6)+(1*8)=118
118 % 10 = 8
So 6492-68-8 is a valid CAS Registry Number.
