Check Digit Verification of cas no
The CAS Registry Mumber 6535-42-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6535-42:
(6*6)+(5*5)+(4*3)+(3*5)+(2*4)+(1*2)=98
98 % 10 = 8
So 6535-42-8 is a valid CAS Registry Number.
