137715-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137715-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,1 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137715-24:
(8*1)+(7*3)+(6*7)+(5*7)+(4*1)+(3*5)+(2*2)+(1*4)=133
133 % 10 = 3
So 137715-24-3 is a valid CAS Registry Number.
