64245-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64245-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,4 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64245-92:
(7*6)+(6*4)+(5*2)+(4*4)+(3*5)+(2*9)+(1*2)=127
127 % 10 = 7
So 64245-92-7 is a valid CAS Registry Number.
