134938-95-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134938-95-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134938-95:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*8)+(2*9)+(1*5)=157
157 % 10 = 7
So 134938-95-7 is a valid CAS Registry Number.
