120523-94-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120523-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,2 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120523-94:
(8*1)+(7*2)+(6*0)+(5*5)+(4*2)+(3*3)+(2*9)+(1*4)=86
86 % 10 = 6
So 120523-94-6 is a valid CAS Registry Number.
