1204388-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1204388-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,3,8 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1204388-52:
(9*1)+(8*2)+(7*0)+(6*4)+(5*3)+(4*8)+(3*8)+(2*5)+(1*2)=132
132 % 10 = 2
So 1204388-52-2 is a valid CAS Registry Number.
