121241-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121241-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121241-75:
(8*1)+(7*2)+(6*1)+(5*2)+(4*4)+(3*1)+(2*7)+(1*5)=76
76 % 10 = 6
So 121241-75-6 is a valid CAS Registry Number.
