134290-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134290-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134290-57:
(8*1)+(7*3)+(6*4)+(5*2)+(4*9)+(3*0)+(2*5)+(1*7)=116
116 % 10 = 6
So 134290-57-6 is a valid CAS Registry Number.
