137906-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137906-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,0 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137906-16:
(8*1)+(7*3)+(6*7)+(5*9)+(4*0)+(3*6)+(2*1)+(1*6)=142
142 % 10 = 2
So 137906-16-2 is a valid CAS Registry Number.
