850221-86-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850221-86-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,2,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 850221-86:
(8*8)+(7*5)+(6*0)+(5*2)+(4*2)+(3*1)+(2*8)+(1*6)=142
142 % 10 = 2
So 850221-86-2 is a valid CAS Registry Number.
