121587-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121587-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121587-72:
(8*1)+(7*2)+(6*1)+(5*5)+(4*8)+(3*7)+(2*7)+(1*2)=122
122 % 10 = 2
So 121587-72-2 is a valid CAS Registry Number.
