858280-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858280-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,2,8 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 858280-90:
(8*8)+(7*5)+(6*8)+(5*2)+(4*8)+(3*0)+(2*9)+(1*0)=207
207 % 10 = 7
So 858280-90-7 is a valid CAS Registry Number.
