137305-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137305-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,0 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137305-72:
(8*1)+(7*3)+(6*7)+(5*3)+(4*0)+(3*5)+(2*7)+(1*2)=117
117 % 10 = 7
So 137305-72-7 is a valid CAS Registry Number.
