865716-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 865716-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,7,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 865716-90:
(8*8)+(7*6)+(6*5)+(5*7)+(4*1)+(3*6)+(2*9)+(1*0)=211
211 % 10 = 1
So 865716-90-1 is a valid CAS Registry Number.
