148315-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148315-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,3,1 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 148315-85:
(8*1)+(7*4)+(6*8)+(5*3)+(4*1)+(3*5)+(2*8)+(1*5)=139
139 % 10 = 9
So 148315-85-9 is a valid CAS Registry Number.
