156301-09-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156301-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,0 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156301-09:
(8*1)+(7*5)+(6*6)+(5*3)+(4*0)+(3*1)+(2*0)+(1*9)=106
106 % 10 = 6
So 156301-09-6 is a valid CAS Registry Number.
