64526-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64526-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,2 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64526-50:
(7*6)+(6*4)+(5*5)+(4*2)+(3*6)+(2*5)+(1*0)=127
127 % 10 = 7
So 64526-50-7 is a valid CAS Registry Number.
