1262286-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262286-40-7 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, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1262286-40:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*8)+(3*6)+(2*4)+(1*0)=147
147 % 10 = 7
So 1262286-40-7 is a valid CAS Registry Number.
