131244-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131244-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,4 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131244-87:
(8*1)+(7*3)+(6*1)+(5*2)+(4*4)+(3*4)+(2*8)+(1*7)=96
96 % 10 = 6
So 131244-87-6 is a valid CAS Registry Number.
