1010720-59-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1010720-59-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,0,7,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1010720-59:
(9*1)+(8*0)+(7*1)+(6*0)+(5*7)+(4*2)+(3*0)+(2*5)+(1*9)=78
78 % 10 = 8
So 1010720-59-8 is a valid CAS Registry Number.
