124093-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124093-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,9 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124093-85:
(8*1)+(7*2)+(6*4)+(5*0)+(4*9)+(3*3)+(2*8)+(1*5)=112
112 % 10 = 2
So 124093-85-2 is a valid CAS Registry Number.
