Check Digit Verification of cas no
The CAS Registry Mumber 76842-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,4 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76842-87:
(7*7)+(6*6)+(5*8)+(4*4)+(3*2)+(2*8)+(1*7)=170
170 % 10 = 0
So 76842-87-0 is a valid CAS Registry Number.
