130649-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130649-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130649-92:
(8*1)+(7*3)+(6*0)+(5*6)+(4*4)+(3*9)+(2*9)+(1*2)=122
122 % 10 = 2
So 130649-92-2 is a valid CAS Registry Number.
