406938-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 406938-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,9,3 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 406938-52:
(8*4)+(7*0)+(6*6)+(5*9)+(4*3)+(3*8)+(2*5)+(1*2)=161
161 % 10 = 1
So 406938-52-1 is a valid CAS Registry Number.
