1147495-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1147495-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,4,9 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1147495-20:
(9*1)+(8*1)+(7*4)+(6*7)+(5*4)+(4*9)+(3*5)+(2*2)+(1*0)=162
162 % 10 = 2
So 1147495-20-2 is a valid CAS Registry Number.
