402941-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402941-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,9,4 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 402941-59:
(8*4)+(7*0)+(6*2)+(5*9)+(4*4)+(3*1)+(2*5)+(1*9)=127
127 % 10 = 7
So 402941-59-7 is a valid CAS Registry Number.
