1266559-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1266559-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,5,5 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1266559-07:
(9*1)+(8*2)+(7*6)+(6*6)+(5*5)+(4*5)+(3*9)+(2*0)+(1*7)=182
182 % 10 = 2
So 1266559-07-2 is a valid CAS Registry Number.
