Check Digit Verification of cas no
The CAS Registry Mumber 6625-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6625-46:
(6*6)+(5*6)+(4*2)+(3*5)+(2*4)+(1*6)=103
103 % 10 = 3
So 6625-46-3 is a valid CAS Registry Number.
