131675-50-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131675-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131675-50:
(8*1)+(7*3)+(6*1)+(5*6)+(4*7)+(3*5)+(2*5)+(1*0)=118
118 % 10 = 8
So 131675-50-8 is a valid CAS Registry Number.
