Check Digit Verification of cas no
The CAS Registry Mumber 2978-90-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2978-90:
(6*2)+(5*9)+(4*7)+(3*8)+(2*9)+(1*0)=127
127 % 10 = 7
So 2978-90-7 is a valid CAS Registry Number.
