121503-46-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121503-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121503-46:
(8*1)+(7*2)+(6*1)+(5*5)+(4*0)+(3*3)+(2*4)+(1*6)=76
76 % 10 = 6
So 121503-46-6 is a valid CAS Registry Number.
