156301-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156301-10-9 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, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156301-10:
(8*1)+(7*5)+(6*6)+(5*3)+(4*0)+(3*1)+(2*1)+(1*0)=99
99 % 10 = 9
So 156301-10-9 is a valid CAS Registry Number.
