Check Digit Verification of cas no
The CAS Registry Mumber 137818-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137818-40:
(8*1)+(7*3)+(6*7)+(5*8)+(4*1)+(3*8)+(2*4)+(1*0)=147
147 % 10 = 7
So 137818-40-7 is a valid CAS Registry Number.
