137265-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137265-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,6 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137265-67:
(8*1)+(7*3)+(6*7)+(5*2)+(4*6)+(3*5)+(2*6)+(1*7)=139
139 % 10 = 9
So 137265-67-9 is a valid CAS Registry Number.
