64773-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64773-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,7 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64773-90:
(7*6)+(6*4)+(5*7)+(4*7)+(3*3)+(2*9)+(1*0)=156
156 % 10 = 6
So 64773-90-6 is a valid CAS Registry Number.
