137208-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137208-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,0 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137208-41:
(8*1)+(7*3)+(6*7)+(5*2)+(4*0)+(3*8)+(2*4)+(1*1)=114
114 % 10 = 4
So 137208-41-4 is a valid CAS Registry Number.
