70643-29-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70643-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,4 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70643-29:
(7*7)+(6*0)+(5*6)+(4*4)+(3*3)+(2*2)+(1*9)=117
117 % 10 = 7
So 70643-29-7 is a valid CAS Registry Number.
