850195-85-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850195-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,1,9 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 850195-85:
(8*8)+(7*5)+(6*0)+(5*1)+(4*9)+(3*5)+(2*8)+(1*5)=176
176 % 10 = 6
So 850195-85-6 is a valid CAS Registry Number.
