131558-79-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131558-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131558-79:
(8*1)+(7*3)+(6*1)+(5*5)+(4*5)+(3*8)+(2*7)+(1*9)=127
127 % 10 = 7
So 131558-79-7 is a valid CAS Registry Number.
