1262437-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262437-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,4,3 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1262437-50:
(9*1)+(8*2)+(7*6)+(6*2)+(5*4)+(4*3)+(3*7)+(2*5)+(1*0)=142
142 % 10 = 2
So 1262437-50-2 is a valid CAS Registry Number.
