1521221-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1521221-81-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,2,1,2,2 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1521221-81:
(9*1)+(8*5)+(7*2)+(6*1)+(5*2)+(4*2)+(3*1)+(2*8)+(1*1)=107
107 % 10 = 7
So 1521221-81-7 is a valid CAS Registry Number.
