1315460-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1315460-97-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,4,6 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1315460-97:
(9*1)+(8*3)+(7*1)+(6*5)+(5*4)+(4*6)+(3*0)+(2*9)+(1*7)=139
139 % 10 = 9
So 1315460-97-9 is a valid CAS Registry Number.
