Check Digit Verification of cas no
The CAS Registry Mumber 137089-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137089-49:
(8*1)+(7*3)+(6*7)+(5*0)+(4*8)+(3*9)+(2*4)+(1*9)=147
147 % 10 = 7
So 137089-49-7 is a valid CAS Registry Number.
