1256262-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256262-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,6 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1256262-87:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*6)+(3*2)+(2*8)+(1*7)=159
159 % 10 = 9
So 1256262-87-9 is a valid CAS Registry Number.
