148902-85-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148902-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,9,0 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 148902-85:
(8*1)+(7*4)+(6*8)+(5*9)+(4*0)+(3*2)+(2*8)+(1*5)=156
156 % 10 = 6
So 148902-85-6 is a valid CAS Registry Number.
