121507-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121507-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,0 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121507-59:
(8*1)+(7*2)+(6*1)+(5*5)+(4*0)+(3*7)+(2*5)+(1*9)=93
93 % 10 = 3
So 121507-59-3 is a valid CAS Registry Number.
