Check Digit Verification of cas no
The CAS Registry Mumber 279693-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,9,6,9 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 279693-87:
(8*2)+(7*7)+(6*9)+(5*6)+(4*9)+(3*3)+(2*8)+(1*7)=217
217 % 10 = 7
So 279693-87-7 is a valid CAS Registry Number.
