1519051-11-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1519051-11-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,9,0,5 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1519051-11:
(9*1)+(8*5)+(7*1)+(6*9)+(5*0)+(4*5)+(3*1)+(2*1)+(1*1)=136
136 % 10 = 6
So 1519051-11-6 is a valid CAS Registry Number.
