Check Digit Verification of cas no
The CAS Registry Mumber 139765-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,6 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139765-18:
(8*1)+(7*3)+(6*9)+(5*7)+(4*6)+(3*5)+(2*1)+(1*8)=167
167 % 10 = 7
So 139765-18-7 is a valid CAS Registry Number.
