137206-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137206-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,0 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137206-90:
(8*1)+(7*3)+(6*7)+(5*2)+(4*0)+(3*6)+(2*9)+(1*0)=117
117 % 10 = 7
So 137206-90-7 is a valid CAS Registry Number.
