70250-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70250-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,5 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70250-64:
(7*7)+(6*0)+(5*2)+(4*5)+(3*0)+(2*6)+(1*4)=95
95 % 10 = 5
So 70250-64-5 is a valid CAS Registry Number.
