131122-70-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131122-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,2 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131122-70:
(8*1)+(7*3)+(6*1)+(5*1)+(4*2)+(3*2)+(2*7)+(1*0)=68
68 % 10 = 8
So 131122-70-8 is a valid CAS Registry Number.
