132715-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132715-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,1 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132715-31:
(8*1)+(7*3)+(6*2)+(5*7)+(4*1)+(3*5)+(2*3)+(1*1)=102
102 % 10 = 2
So 132715-31-2 is a valid CAS Registry Number.
