151005-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151005-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,0,0 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151005-23:
(8*1)+(7*5)+(6*1)+(5*0)+(4*0)+(3*5)+(2*2)+(1*3)=71
71 % 10 = 1
So 151005-23-1 is a valid CAS Registry Number.
