70872-45-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70872-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70872-45:
(7*7)+(6*0)+(5*8)+(4*7)+(3*2)+(2*4)+(1*5)=136
136 % 10 = 6
So 70872-45-6 is a valid CAS Registry Number.
