1240655-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240655-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,6,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240655-75:
(9*1)+(8*2)+(7*4)+(6*0)+(5*6)+(4*5)+(3*5)+(2*7)+(1*5)=137
137 % 10 = 7
So 1240655-75-7 is a valid CAS Registry Number.
