70874-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70874-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,7 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70874-21:
(7*7)+(6*0)+(5*8)+(4*7)+(3*4)+(2*2)+(1*1)=134
134 % 10 = 4
So 70874-21-4 is a valid CAS Registry Number.
