1005498-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1005498-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,4,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1005498-53:
(9*1)+(8*0)+(7*0)+(6*5)+(5*4)+(4*9)+(3*8)+(2*5)+(1*3)=132
132 % 10 = 2
So 1005498-53-2 is a valid CAS Registry Number.
