1026307-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026307-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,3,0 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1026307-52:
(9*1)+(8*0)+(7*2)+(6*6)+(5*3)+(4*0)+(3*7)+(2*5)+(1*2)=107
107 % 10 = 7
So 1026307-52-7 is a valid CAS Registry Number.
