85639-85-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85639-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85639-85:
(7*8)+(6*5)+(5*6)+(4*3)+(3*9)+(2*8)+(1*5)=176
176 % 10 = 6
So 85639-85-6 is a valid CAS Registry Number.
