158148-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158148-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,1,4 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158148-16:
(8*1)+(7*5)+(6*8)+(5*1)+(4*4)+(3*8)+(2*1)+(1*6)=144
144 % 10 = 4
So 158148-16-4 is a valid CAS Registry Number.
