121558-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121558-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,5 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121558-30:
(8*1)+(7*2)+(6*1)+(5*5)+(4*5)+(3*8)+(2*3)+(1*0)=103
103 % 10 = 3
So 121558-30-3 is a valid CAS Registry Number.
