Check Digit Verification of cas no
The CAS Registry Mumber 6655-95-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,5 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6655-95:
(6*6)+(5*6)+(4*5)+(3*5)+(2*9)+(1*5)=124
124 % 10 = 4
So 6655-95-4 is a valid CAS Registry Number.
