1220-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220-87-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1220-87:
(6*1)+(5*2)+(4*2)+(3*0)+(2*8)+(1*7)=47
47 % 10 = 7
So 1220-87-7 is a valid CAS Registry Number.
