708245-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 708245-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,8,2,4 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 708245-31:
(8*7)+(7*0)+(6*8)+(5*2)+(4*4)+(3*5)+(2*3)+(1*1)=152
152 % 10 = 2
So 708245-31-2 is a valid CAS Registry Number.
