850764-58-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850764-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,7,6 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 850764-58:
(8*8)+(7*5)+(6*0)+(5*7)+(4*6)+(3*4)+(2*5)+(1*8)=188
188 % 10 = 8
So 850764-58-8 is a valid CAS Registry Number.
