121056-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121056-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121056-87:
(8*1)+(7*2)+(6*1)+(5*0)+(4*5)+(3*6)+(2*8)+(1*7)=89
89 % 10 = 9
So 121056-87-9 is a valid CAS Registry Number.
