120572-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120572-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120572-74:
(8*1)+(7*2)+(6*0)+(5*5)+(4*7)+(3*2)+(2*7)+(1*4)=99
99 % 10 = 9
So 120572-74-9 is a valid CAS Registry Number.
