158380-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158380-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,3,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158380-45:
(8*1)+(7*5)+(6*8)+(5*3)+(4*8)+(3*0)+(2*4)+(1*5)=151
151 % 10 = 1
So 158380-45-1 is a valid CAS Registry Number.
