Check Digit Verification of cas no
The CAS Registry Mumber 6637-87-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6637-87:
(6*6)+(5*6)+(4*3)+(3*7)+(2*8)+(1*7)=122
122 % 10 = 2
So 6637-87-2 is a valid CAS Registry Number.
