84986-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84986-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,8 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84986-64:
(7*8)+(6*4)+(5*9)+(4*8)+(3*6)+(2*6)+(1*4)=191
191 % 10 = 1
So 84986-64-1 is a valid CAS Registry Number.
