1262286-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262286-39-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,8 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1262286-39:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*8)+(3*6)+(2*3)+(1*9)=154
154 % 10 = 4
So 1262286-39-4 is a valid CAS Registry Number.
