Check Digit Verification of cas no
The CAS Registry Mumber 6507-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6507-83:
(6*6)+(5*5)+(4*0)+(3*7)+(2*8)+(1*3)=101
101 % 10 = 1
So 6507-83-1 is a valid CAS Registry Number.
