1269761-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269761-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,7,6 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1269761-59:
(9*1)+(8*2)+(7*6)+(6*9)+(5*7)+(4*6)+(3*1)+(2*5)+(1*9)=202
202 % 10 = 2
So 1269761-59-2 is a valid CAS Registry Number.
